Yeah, I was working in a science lab around that time and the lab was doing work for DARPA, and I was friends with a young couple both PhD.s and probably both with clearances to work in the program. They both adamantly refused to join Fakebook, never said why. Just unh-unh. I’ve wondered lately if they didn’t get tip offs about it at some of the conferences and stuff that they would go to.
Of course little did they know SuckBook and goolag had ways to peek our your smartphone whether you installed them or not.
They Knew!
I never joined Facebook either. Glad I resisted when friends/relatives said I was missing out on family/friends news and pictures.
Re: Facebook -had a similar thing happen, only after the fact. I had an academic friend in Europe who suddenly decided to remove all his Facebook data and start his own platform. He had discovered the data collection aspect.
