Snowden's revelation of US surveillance infrastructure more than 10 years ago doesn't really change much of people's perspective about privacy. Should be no surprise that people are still on facebook platforms.

I'm not from US, probably most of my friends don't know about Snowden, surveillance capitalism, and such. Some other people are already struggling enough with their daily shit to care about their online privacy.

And those infrastructure is also most useful to fight against journalist, US adversaries/critics, etc, than ordinary people.
