Thing is, from what I can tell, more or less all "smart TVs" are just totally spyware-infested.
It's the economics - particularly on the low end, where you can find economy brand 60"+ TVs selling for a few hundred dollars - they're selling the TV for barely any profit (possibly even at a loss) as you cart it out the door, and they're expecting to make it all up by selling data about you and your viewing habits (on an ongoing basis), and/or making a commission when you buy movies/shows (or sign up for streaming subscriptions) through their "smart TV" interface.
Average Joe Consumer sees two 70" TVs on the wall at Best Buy, both with super vivid overdriven pictures - if one is a couple hundred dollars less (because it sells data about him), he's not going to have any thought of ACR (and might not care if he did), he's gonna think he's a savvy consumer by buying the TV with the lower price tag. So, once one manufacturer went that direction, it was inevitable the others would follow. (First hits on Google for "low priced big screen tv" are for Best Buy's house brand: $300 for 65", $350 for 70".)
I'd love to see a brand present themselves / their TV models as the "non-creepy privacy-focused" alternative, charging more upfront for great hardware with a modest profit. But the established brands can't do that with only some of their models, because then everyone would say, "uh, so you're admitting your other TVs do creepy data collection?". And it's a very risky proposition for a startup brand.
The major brands have much less justification for having such software on their premium models. Eh, once they find a way to make money it's hard to convince them to not use it. I have a nice LG (C1), with all of the invasive ToS agreements
declined (which means most of the "smart" features are non-functional), running as basically a very effective monitor (that is
not connected to the internet), with nearly all content coming from my Apple TV and PS5.
