Google is now deleting all accounts that do not, and have never had, phone numbers associated with them if they haven't logged in within a year or so.

"Urgent: Sign in to your Google Account if you want to keep it"

But then it doesn't matter if you log in with the correct username and password and receive the PIN via your email. This is isn't enough. Unless a phone number is somehow added to the account one gets,

"You can’t recover your account at this time because Google doesn’t have enough info to be sure this account is yours."

This is despite having all information ever associated with the account. Unless that account has a phone number it will be deleted. This is a very shady dark pattern by Alphabet corporation.

Advertising company (Doubleclick [1]) wants phone numbers to better target ads. No surprise there.

[1] The company currently calling itself Google is not the same Google as yesteryear. In 2008 Google purchased Doubleclick, and what happened is that the advertising rot from Doubleclick ate Google from the inside out. What we have now calling itself Google is actually all the evil that was Doubleclick, only calling itself Google. That's why the Google motto no longer includes "Don't be evil".

Steam gave me similar problems. In the process of trying to get in for the first time in a while to delete my account, I completed a successful 2FA but still couldn't log in because I had to prove I owned the account by providing extra information.

We've fallen so far from the days when the retailer let you just have the game you bought and then they were out of the picture forever.

put my same phone number on 10+ google accounts, if you're skipping this you look like a bot, how should google be able to tell you apart from all of the bots.

I've often read that 2FA should be through an authenticator app or a physical key, not via texting a code to a phone number. Malicious sim swapping is a thing, so purposely deleting any phone number from an account should be good practice, right?

So will they also delete inactive accounts that have no phone number, but one or more phone-less 2FA methods associated?

There's no reason to use Google over ProtonMail or Tuta Mail if you care about user experience. Google's customer support is non-existent, while Proton and Tuta will get you a real human for any problems and are accountable.

Yes, I’ve lost access to two old accounts including my old blogger one. When I try to log in it sends email saying, “someone tried to log in with your password!” :-/

It's phonishness. Your life isn't real unless you have a smartphone -- at least that's the way "the empire" sees it.

if you haven't cared about using an account for a year, why do you want to use it all of a sudden now?

Not providing your phone number is a critical step in protecting yourself against sim swap attacks and other vulnerabilities.
