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.
I think it’s more that you have to purchase the item before you can agree to the EULA. That said, it’s extremely rare for anyone to try and challenge them in court, and when they do they pretty much always settle so the court can’t actually demand any changes to EULAs.
