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.
A lot of TVs these days won't start working without wifi. I set up a temporary ssid, set up the TV then delete it.
Hooking it up once is one thing, but actively using the Internet connectivity is just begging these companies to screw you over. That being said, I'd sooner bring it back to the store and get a different one than let it phone home even once.
