Google is probably the most aggressive anti-privacy big tech company currently operating.

No other big-tech company goes to such great lengths to deanonymize users and make its services difficult to use, especially during account creation.

The requirement to have a mobile device to scan a QR code to verify that you're human. Reverse SMS verification, where you have to send an SMS rather than receive a verification code. You think of signing up using a VPN server in another country? The phone number you use to send the SMS from must also be from that country.

Not being able to watch YouTube videos when using VPN - without signing in to a Google account, all under the guise of "bot protection."

Gemini not working in 3/4 of cases when using VPN.

It's essentially almost impossible to create a Google account without giving up your identity, and your phone number often leads directly to your real-life identity.

I'm not sure what happened in recent years, but they definitely switched their strategy to maximize data collection and make sure privacy-savy users are pressured via technical solutions to reveal their identities.

PS. The first company federal investigators often go for data is often Google

Trying to fight it takes an enormous amount of time and energy. I carry two phones now - since I have my "privacy" enabled phone that basically has nothing on it. Email, messages, weather app and a few privacy enabled browsers. My other phone has all my "faux" google stuff on it. Maps, gmail, banking apps, my authenticator apps, music apps, etc.

Even then, these can all be tied together fairly easy, but just trying to make it harder to keep my data private is such a battle; and friends always ask me why I spend so much time trying to keep myself anonymous when in 2026 its virtually impossible to do so.

I always tell them: “Bene vixit, bene qui latuit.” (To live well is to live concealed.)

▲Waterluvian 4 hours ago | parent [-]

This all sounds completely sensible. And yet, being caught by the police with two phones would probably be a big stupid red flag for them.

▲mixdup 4 hours ago | parent | next [-]

Having two phones is more common than you think, and has a very plausible explanation even if it's not true for the particular individual: One is my work phone, issued by my company, other one is mine

That happens all the time

▲noah_buddy 3 hours ago | parent [-]

Unless you’re clever about setting up the phones to match your excuse, you are now lying to the police as well.

▲SllX 3 hours ago | parent | next [-]

Follow the usernames in the response chain. I have two phones for the exact same reason as well: work issued & personal. It would hold up just because it’s actually true. There’s no need to arrange anything beyond how they are naturally arranged.

It's crazy that the police can lie to you.

By rights the simple comeback is they can lie to you so F'em.

The real answer is you don't offer any explaination because it's not something you need to explain or get anyone's permission for.

Feel free to wonder. Give me a hard time and I'll just do my best to give you a hard time back. After you confiscate my stuff and detain me and I turn out not to have broken any laws, I'll do everything I can think of to extract an apology and compensation and penalty. Afro Man is my hero. You will become my new career.

That's my little fantasy anyway but I do see it as a duty to at least resist a little. In reality I'll fold pretty easy but I will be as much sand in the gears as I can.

In Uganda carrying two phones is completely normal. Many people have one for work and one for personal use, or simply because they can afford a second phone. Police wouldn't think twice about it.

> It's essentially almost impossible to create a Google account without giving up your identity, and your phone number often leads directly to your real-life identity.

I had a Gmail account before they required phone numbers. One day, Google stopped allowing me to log in, demanding my phone number if I wanted to continue. Nothing was wrong with my credentials, or behavior patterns, or IP address, or anything at all. My already-registered recovery email address didn't help. There was no way to appeal.

I'm not willing to have my phone number extorted from me, so I sighed and accepted that I'll never again have use of that account. It remains a constant source of irritation, because it still forwards incoming messages to my home email address, and Google doesn't do a very good job of filtering out all the spam before they forward it my way.

Adding insult to injury, Google still (years later) hasn't made good on their announcement that idle accounts would be deleted. I wish they would. I'm done with Google.

Do you say google over meta because meta has a smaller footprint?

also: you can subscribe to duckduckgo ($99 or $199/year) and that gives you not only VPN access, but DDaaS - Data Deletion as a Service.

(don't know how data deletion works outside of california, but I think california allows global deletion now)

Every scammer, fraudster, scammer-in-training, fraudster-in-training, uses a Google account.

The first company federal investigators often go for data is often Google because that's the start of their lead into their investigation. Google needs to provide answers, sometimes by regulation in countries.

meta comes to mind? you can't even interact with their services unless you have an account, and they ban you if you don't reveal yourself transparently. then they ask you for a state-issued ID to appeal bans. seems like some great lengths to me.

▲margalabargala an hour ago | parent [-]

I agree. Meta is as bad as if not worse than Google.

It is however much easier to navigate life without Meta than without Google. Even if you use different email, etc, if you collaborate with someone on a doc or whatever they are likely to send you a google link.

▲bsammon 4 hours ago | parent | prev | next [-]

> It's essentially almost impossible to create a Google account without giving up your identity, and your phone number often leads directly to your real-life identity.

A process I've gone through a few times (though I didn't actually want a Google Account):

1) Get a new (second-hand sometimes) ChromeOS or Android device.

2) (if necessary) do a power-wash or factory-reset.

3) Do the "set up a new device" process.

4) When it asks you for a Google account, click on the "I don't have one. create a new account" button.

In all these cases, the device didn't (or couldn't, in the case of the Chromebook) have a SIMcard in it, so it couldn't link it to a phone number.

One smartphone that I bought for $20, and never (IIRC) had a SIMCard in, I think the only identity-oriented app I have on it is Netflix. I've wondered if Google links the smartphone's google account to the Netflix account (which is actually not me, but a cousin's), and whether Netflix is complicit in this linking.

I imagine that Google is keeping a log of the ip addresses that phone reports when it's connected to wifi. I There's probably some overlay between you and your known associates / locations.

▲Terr_ an hour ago | parent | next [-]

They also log all the locations where anybody's phone encountered an SSID.

It's unclear whether an SSID suffixed with _nomap truly opts out of the collection, or whether it simply opts out of later sharing.

Even if they don't, the law enforcement definitely does (or rather requires your ISP to).

Gemini doesn't work 10/10 times for me.

Recently its taken over and I can't switch back to Assistant on Android. Now I have timers that run for a bit and then disappear, and whenever I'm driving and use voice to call it brings up the phone number and requires me to press again to dial.

Absolutely frustrating and I don't understand how this can be pushed as the default.

I can only assume its another scenario where they disable all the features because I'm not in the US, but then never tested it.

▲jambalaya8 3 hours ago | parent [-]

Google discontinued Assistant in the first week of September, 2026; it was ostensibly 'replaced' by Gemini then. They should have allowed both until the kinks were worked out of Gemini.

They also attached to a VERY HIGH NUMBER of ip addresses when you launch Chrome. Run an application level firewall and look at Chrome's behavior on startup. So many that I think they are geolocating users, even across VPNs

isnt that their only business model almost from day 1? Everyone shitting on Meta because of privacy but Google's the worst.

▲achenet 2 hours ago | parent [-]

the original business model was, if I'm not mistaken, licensing the search technology.

Then they found that showing ads with the search results made them a lot more money.

They started optimizing for money made from ads, which depends on user data - letting advertisers show ads to targeted customers.

Have you noticed the front page article sharing front page real estate with this one about Big Tech getting in trouble for not doing more to stop scamming and fraudsters?

https://www.theguardian.com/us-news/2026/oct/14/dating-app-s...

Regulators want Big Tech to stop children from doing various things (such as access certain platforms or content), to stop fraudsters and scammers, to stop foreign intelligence operations or bots from astroturfing social media/manipulating social discourse, and so on.

Failing to so leads to inquiries, new laws or regulations, fines, and so on.

The technical solutions to combat these problems are the exact solutions that also ruin privacy for users, create friction at account creation time, require ever more draconian identity verification methods and so on. It's 1:1.

"I'm not sure what happened in recent years, but they definitely switched their strategy to maximize data collection and make sure privacy-savy users are pressured via technical solutions to reveal their identities."

It's really not any more complicated than that Governments have told them its time to start violating users privacy in order to combat these other problems.

It really bothers me that every dick and jane website has normalized asking for your personal phone number. It's the first thing they ask when you sign up. At this point your phone number has become your social security number of the internet.

I don't care if fighting fraud is hard for you. Figure it out without stripping away my privacy.

A lot of them also block voip numbers. This is obviously just a way to collect cell numbers that are easy to send spam SMS messages to.

▲Cider9986 2 hours ago | parent | prev | next [-]

Yeah, phone numbers are essentially KYC. I use a phone number verification site, but I can't recommend them because they stopped accepting Monero recently.

For long term numbers I would use jmp.chat.

▲pkulak an hour ago | parent [-]

Google knows all about virtual phone numbers and won't accept them. If you don't have a number issued by a large telco, forget about creating a Google account.

▲Cider9986 an hour ago | parent [-]

JMP is a real carrier number so it should work better for 2fa than VoIP numbers.

I haven't used it yet, but I'm switching to it once my current plan runs out. There's plenty of options for data.

▲_ink_ 36 minutes ago | parent | prev [-]

It's super annoying, because it's normally also a path for account recovery. So if you need to change your number, good luck remembering where you have signed up with it.

▲rdtsc 5 hours ago | parent | prev | next [-]

That's why I stay away from trying Gemini or doing anything much with Google until I still host my main gmail account there. One misstep and I'll find myself locked out. Because it's Google's job to spy on everyone, if I have other accounts there, those will also locked out too ("oh! you're trying to circumvent our ban? we noticed!" kind of a thing). Then the only recourse from what I understand is to make an HN post and hope it makes it to the front page and someone from Google who knows someone else at Google will help you.

▲SoftTalker 3 hours ago | parent | prev | next [-]

The biggest player in ad tech also being the biggest provider of mobile phone operating systems and web browser and web search and email services was only ever going to end up this way. I'm not a big fan of regulation but at some point a single corporate entity should not be allowed to control all of the things.

▲rlpb an hour ago | parent | prev | next [-]

I always assumed that if I add other Google accounts to my Android phone then they'd be linked together, so I avoided doing it. It's a pain because Google apps require it. For example I can't join a Google Meet from my phone for this reason because I've always kept the Google account I use for email separate from the Google account I use for Android (and then K-9 Mail via IMAP to access it to avoid connecting them there).

Ironically this means that my experience with Google apps on my Android phone has always been poor but other vendors' stuff work fine. For example I use Fastmail for some key email addresses and this works well for me whereas I cannot use the Gmail app.

I guess I made the right choice.

The problem this can cause is that it could become the root identity for the effective social credit system. For example, if Uber bans you (it happens..), you might need a new phone number and email to get around it. At least you can get around it for now.

▲exabrial 4 hours ago | parent | prev | next [-]

Our corporate policy doesn't allow personal phones to be linked to corp accounts, for obvious reasons. We have no idea what kind of security your personal phone number has setup, nor do we compensate employees for their personal phones, nor do we want corporate communications happening on your personal device (work/life separation).

If the vendor is unable to comply, all we're using them for is email. Time to look elsewhere.

▲Cider9986 2 hours ago | parent | prev | next [-]

Sure, it's bad Google is anti-privacy and they're trying to stop you making an anonymous account, but that is their business model.

You're much better off using and supporting privacy focused services [1] instead of trying to make Google private. I do not have any Google accounts I depend on–I deleted all of them that I'd used personally, and now I only have attempts at anonymous accounts.

I wouldn't rely on them even if I wasn't constantly getting banned because they have no customer support, no E2EE, they scan your photos, it's insanity.

▲anygivnthursday 4 hours ago | parent | prev | next [-]

Is it silent, though? I got notifactions about it on my devices, then emails on each account. Then I went straight to delete the added numbers and disabled this "feature". It did not leave a good taste that I had to do this after the fact, I would have appreciated a notice with a chance to opt out first, because they may have already permanently stored those numbers in some internal history (I just asked Dropbox for my data and they listed every single email I've ever used on that account too). But, to be honest, I am not surprised, and I already consider all devices and numbers that ever come into contact with a Google account being permanently on record on some Google server.

Just the other day I tried to log into the Google account I have connected only to this HN account, and Google asked me to use the account linked to the backup email address on that account to verify my login, then logged me into that account on my phone when I used it to verify my login.

This isn't the behavior I observe on my phone.

All my SIMs I've used in my phone seem to have been added as verified phone numbers to my primary account, but my secondary accounts don't have any phone numbers still.

It's still somewhat obnoxious since it means random travel sims that could get reused after they expire are "verified" for my account.

Google is not so silently deleting the accounts (gmail, etc) of anyone that has not given them a phone number to link and generate information sales profit from. It happened to my gmail account and there was nothing I could do, short of supplying a phone number, to stop it.

I don't think this is new. If you have ever gotten a "fuck off and die" letter from AdSense after like 2010 or so, then you know they will correlate your identity and ban your other accounts too. They don't ban accounts, they ban people.
