Not to be defeatist, but I'm just a guy. Nobody's gonna listen to my demands. I'm surprised privacy notifications say anything other than "You don't have any" with two buttons that both say "OK". All I can do is selfhost as much as possible and decline to use tons of applications or services that underpin modern societal functions or social activities. So I do. But it sucks ass and I don't have any power to change any of it.
Where I am, unlike climate change, the privacy issue is not discussed properly so just explaining it to people that trust you can boost any future systemic action.
No, but the point they're trying to make is, I think, that the more you complain, the more other people complain and the more other people start complaining and unless we have enough complainers and people switching, nothing is gonna change.
