It was blatantly obvious to me within a few years that FB had no interest in thinking through the implications of data sharing. There was a time when a friend liking a picture of their friend would show up in my news feed and clicking through it would expose the entire album to me - who is not even remotely connected to that person. That's the day I went frantically removing photos of friends and coworkers from FB and eventually all of mine as well. Facebook is very unlikely to earn back my trust ever.
