Part of the reason why I take good care of my little 24" dumb TV. It’s on the lower end (poor viewing angles, absolutely no adjustment on the legs) but I still have a use for it, so I won’t be replacing it.

The other concern I have with smart TVs is because manufacturers basically install a smartphone SoC, the TV’s lifecycle is now the same as a smartphone. Most people probably won’t connect a new smart TV box to their discontinued, laggy (thanks to bloated apps) smart TV, the completely functional unit just gets replaced.
