Average person does not understand why privacy is important. They were lucky enough not to (yet) experience repression, censorship or surveillance and often throw banal one liners like I've got nothing to hide.
It's only once you lived a while with someone (person or an institution) watching your every step you realize how it definitely changes you. You decide not to state your opinion, not to raise your hand, not to make the choice you would of you were truly free.
Same goes for welcoming your data against you.... But you're on fediverse. I'm packing to the choir here.
