I deactivated, not deleted from FB. The questions they asked as I left were manipulative enough that I almost switched to full delete.
I wasted too much time there, providing entertainment but not receiving much. I will miss the C S Lewis group, though that could be a pain sometimes as well. I was already worried about privacy and use of my information, and the recent revelations didn't help. But it was Zuckerberg's misdirected apology, so terribly sorry he had let Trump do the bad things he had helped Obama do in 2012, that convinced me to pull the trigger. I grant there were some differences in that, but not enough to change the overall actions.
So I knew I couldn't trust them to do the right thing when the chips were down. Final straw. I lived without it for 60 years, I imagine I will muddle along somehow now, eh?
