people who continue using Meta apps because... [whatever], are directly harming all other people who want to opt out of this mass surveillance monster.

Private photos or videos of events and social situations will involve many other people, people that never consented to be data mined in Meta's evil social graph.

Its the equivalent of getting cancer from passive smoking because somebody refuses to tackle their addiction and thereby inflicts damage on others.

Stop giving content/money/profits to the oligarchs.
