Should also be applicable if you have to have an online account with a 3rd party service to use a product, as I experienced with the NVIDIA Shield[0]
At the same time, "not agreeing with the EULA" is a valid reason to return a product to the store, as I did. Consumer protection laws would be on your side here, in the jurisdictions I'm aware of (Canada/US)
EULAs like this should be illegal. Comparable to "Warranty void if this sticker is damaged" type scenarios.
The enormous "gotcha" games being played under the guise of "if it's not illegal, we're going to exploit it" are grotesque. TVs are just one of hundreds of examples of products and services being used to invade and exploit privacy with no commensurate return on value for what's being exploited.
We need a law constraining this shit to 100% opt-in voluntary features with no dark patterns, with penalties for anything that even vaguely looks like a dark pattern. Fines and jail time time for c-suite for any violations, enough that they'll stop playing the stupid games.
Or just back to the retailer and tell them why you're returning it. If they put up an argument (which they likely won't), then at least in the US, I think you could sue to be compensated.
If you didn't see and agree to the TOS prior to purchase, and you find the TOS you discover later to be unacceptable, then I'm confident that you'd win in court.
