I've 'deactivated' my Facebook account earlier today actually. Would have deleted it but that hasn't been an option for years.
Facebook is on it's way to a downward spiral. Zucc knows it and that's exactly why he is selling off his shares and it's exactly why Facebook is now putting out commercials in the US saying they're changing the news feed algorithm to display less ads.
It's still a data mining psych opp and will be exposed as one. There's a couple class action lawsuits filed against them as well. Elon Musk was just recently on Twitter (another terrible social site. Gab.ai is superior) trolling FB and Zucc for it's practices. He removed the Tesla page and his personal page combining over 2 million followers/likes.
I'm going to keep my fingers crossed and hope that greedy Zucc and FB get what he/they deserve.
