It seems like there is a big business opportunity for someone to create a box you attach to your network to filter outgoing info, and incoming ads. Too much work for a tiny team to research what everything is talking to, and MITM your devices and watch DNS queries, etc, but if there was something dead simple to block a Samsung fridge from getting to its ad server, I have to think it would sell.

That exists, it's called a pi-hole, and it's very popular. It will block the 'tv spy' apps.

I thought of pi-hole but I’m not sure it is dead simple. I’m thinking a box that your incoming internet connections connects to and an outgoing connection to your wifi router.

The market probably isn’t big enough yet, but I’ll bet it grows. I mean _Texas_ is bringing it up!

		Encryption works against you when the attacker is inside your network. The solution is to keep them out.

I tried using a Pi-hole for this exact reason: prevent bullcrap TV ads. My Roku TV wouldn't stopped working. I had to whitelist so many roku-related domains that it basically became pointless.

		I had the same issue, decided to remove Roku instead… I used to have a Roku TV, plus a a few of the standalone Roku Ultras for my other (non-Roku) TVs. I got a full page advert when I started up the TV one day and started the process of replacing them all (I think it is when Roku were experimenting with that). Over about a year I replaced them with Apple TVs* and the user experience is far better, plus the amount of tracking domains reported by Pi-hole dropped precipitously! The TVs don't have internet access at all, they are just driven via the HDMI port now. * I replaced the Ultras first, and when the Roku TV eventually started acting laggy on the apps I replaced the Roku TV as well.

You probably overestimate the market for something like that. Most people don't know or care. Those that do are more likely to hang out on HN or adjacent places and know how to deal with it themselves anyways.

A sibling comment says "just use Pi-hole" which kind of works and is also inadequate. A similar system is Ad Guard Home. These work at the DNS level with preset lists of bad domains. They aren't necessarily going to catch your TV calling out to notanadserver.samsung.com because that domain name is not recorded in the list of naughty domains. They are definitely not going to help if your device reaches out via IP.

Another approach is to disallow all DNS or only allow *.netflix.com for the TV. In my experience attempting to only allow certain domains is a game of whackamole where everyone in the house complains their stuff is broken because it needs undocumentedrandomdomain.com.

A/B testing/feature flags SDKs, and DRMs (for provisioning keys) come to mind.

Until Samsung builds a fridge that won't cool if it goes more than some period of time (a week?) without pinging their servers. They'd probably get away with it given the friction of getting a large appliance out of your home and back to the store. Bonus evil points for making this feature active only after the return/warranty period expires.
