Replaces them? I don't like FB, but I also don't see anybody seriously freaking out about what they are doing, outside of a few internet forums that most FB users don't read. People freak out and post the clickbait about Cambridge Analytica, and FB pushes the clickbait in persuit of 'engagement' (which is the real underlying issue here), and people like me laugh at their 'psychometrics' bullshit, but in the end none of us are actually going to delete accounts over any of this. I've seen a much larger portion of the userbase even more angry than this when they opened the portal to non-college students and let people make apps. That was a long time ago. This is a global site now. If every American user decided to delete facebook today, FB would lose a little under 10% of their user base. That's it. For FB to shut down, people need to be mad at them globally, or there needs to be a serious alternative. I don't see one yet.

I mean, mastadon is the closest competitor, IMHO, but they aren't ready for prime time yet. When every client is an instance, and there are a few more bells and whistles, then maybe mastadon will compete. Right now, it's a bunch of techie nerds. Nothing wrong with that. Every online community worth mentioning grew from a bunch of techie nerds like this. It just has a long way to go before it challenges facebook.

Yeah, they probably bought and/or traded information with ISPs and Google and credit agencies, and other sources I've probably never heard of. They don't need 3rd party data any more.

GoDaddy didn't reverse their position at all. They are still in support of SOPA. Here is the CEO refusing to come out against the bill:
