Just as an addendum, I think you can still vote with your wallet, even in a world where there are truly no dumb TVs. The vote would be "do not buy a TV." It's an option, and isn't even that big of a deal. As another commenter noted, you can watch TV on your laptop with an ad-blocker, but you can also just read a book. I don't mean this to be rude or combative -- I'm quite serious here. TVs are luxury items in the narrow sense that they're not necessary for anything; they're just leisure. Because of that, it should be possible to completely avoid it. Take up hiking, learn the guitar, read more books, join a social club, etc. No one needs a smart TV.
Crucially, someone who owns a smart TV has implicitly made a claim "the entertainment of TV is more important to me than privacy." That's all I'm saying. I explicitly did NOT mention vehicle privacy because most people do not have a choice about whether they own a vehicle. They need it for work, child care, etc. It is possible to avoid smart vehicles, but it's getting more difficult, and I suspect it will be impossible in the future. (even with a dumb car, there can be license plate scanners in a lot of locations)
