I don’t get the idea that after all the shit they pulled someone’s like “well maybe this new thing’s nice”.
I look at my friends who do this even though I advize them not to. For them, data is invisible and out of sight, out of mind. Their TV is a consumer device like IDK a toaster or washing machien. They put it online with no real thought to data or privacy. From their perspective this is normal. Their neighbors all do it with their TVs. Their friends all do it! I am the only one who makes a warning to them. Everyone else they know does it. Who wouldn't want a "smart" TV???
They don't understand tech very well and they feel like what they see most people doing must be good. They are not thinking about the eroding effect on their whole society from normalizing dragnet surveillance and total privacy loss. It's too abstract, and the allure of the shiny is too much.
I think you are right (today!), but look what happens with cars... the car connects to a wireless network without asking you, to send back telemetry. The cost of doing that is coming down all the time, and there is a big juicy profit stream just waiting to be harvested. I will not be surprised if we see TVs do this eventually, like cars do already.
They could also be designed to simply refuse to function if they can't connect. I didn't hear about any like this so far, but it feels like a matter of time. Enshittification comes for everything.
