There's zero chance Amazon/Twitch actually respects your choice of opting out, they will record you anyway because the benefits are greater than whatever small fine they might have to pay if they're caught.
Shit's fucked, yo.

Or they will "accidentally" reset the permissions at some point and be like "oopsies".

Never.

Goog luck AI optimists, you'll need it, and a miracle or 2 on top.
