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 do not think that this can be legal, if you have already agreed to terms.
Surely they can just say from now on, thing you have used for a year is not usable unless you promise not to sue us.
Surely that ship has sailed?
Where I live, the way contract law (at least in regards to employment) works is generally you can't alter terms (by imposing additional restrictions) after both parties have agreed to it unless there is some form of compensation provided for the restricted party in exchange for agreeing to those additional restrictions.
