What you didn't include: the data gathering and the ads. tons of ads. I interacted with smart TVs before, but when i pay for it and it displays me ads in the UI, its an instant return. I'll have none of that shit.
And don't get me started on weird bugs that i can't even fix myself. Stuff like my dad's TV randomly outputting 1-2 seconds of audio of the last selected sender /while being turned off/. Audio only, with the screen turned off. Just a few moments. Nightmare fuel when its dark and you are sleeping in the same room.
