Actually I take it back, that is what kept changing location. They'd have an opt out but bury it in increasingly arcane places, and of course since it was "different" I was opted back in.

Then I started disabling my wifi and that kept magically re-enabling.

And that's the point I took the nuclear option.

What brand of TV?

Samsung, from about 4 years ago I think

I had a Samsung plasma TV about that long ago and it started to show notifications every time it turned on that some service I never used was being decommissioned.

Same experience as https://us.community.samsung.com/t5/TVs/Annoying-notificatio... but with a different notification.

I don't think I'll buy a Samsung TV again after that, and I don't connect any TV to the internet anymore.

LG does this too. I had to black hole its MAC address in my router.
