"So just don't..." arguments about technology always seem so naive, and this one is no exception. Smart TV manufacturers don't care about edge cases, they care about making sales, developing annual recurring revenue (ARR), and avoiding liability. Acting as a dumb terminal only marginally helps the first item while hindering the latter two. Likely, most manufacturers will probably require you to use an app or their website to setup/register your TV (and to manage it thereafter). Plenty of other consumer products are already following the same path, but the incentives are especially strong for smart TV manufacturers because they load down your TV experience with spyware and injected ads. Want a dumb terminal? You'll be paying a lot more. Perhaps that works for you but the masses will be left behind, which sets the stage for the next wave of corporate overreach/enshittification.
