Did your Roku TV decide to strong arm you into giving up your rights or lose your FULLY FUNCTIONING WORKING TV? Because mine did.
It doesn't matter if you only use it as a dumb panel for an Apple TV, Fire stick, or just to play your gaming console. You either agree or get bent.
So anybody who doesn't have A FUCKING DESKTOP PC near their TV is a Neanderthal?
I have a smart TV from 2019 and it runs perfectly fine, it's snappy and convenient. Switching inputs requires 2 button presses (3 if you don't want to wait 3 seconds to auto-switch to the selected one) or I can automate it with home assistant for a "movie watching" scene for instance, for 0 button presses.
Plus you seem to completely misunderstand what digital signage TV are.
