I love this idea. I'd even do the "buy a smart tv and refuse the agreement so it acts as a dumb tv" if it were certified to be dumb. Otherwise I have absolutely no reason to trust a goddamn television.
They're not even promising me anything; the agreement is a bunch of commitments that I'm making, and they're refusing to provide me their "smart" features because I won't agree to those commitments. That tv can still do whatever it wants to as long as it doesn't break the law in a provable way.
