Look, I'm a developer, I'm somewhat privacy-conscious, and I quit Facebook years ago because they're slimy.

But "doesn't keep up with technology and privacy news" is not the same as "dumb". For any product as big as Facebook, there are people of all kinds using it, including many who are brilliant.

Is it wise to trust Facebook with your data? No. But not having come to that conclusion doesn't make someone dumb. Please don't be so condescending. I'm sure many of those "dumb" people could be condescending about some of your life decisions based on their own expertise. But it's not helpful.
