Facebook exists because Zuckerberg was able to leverage technology and position and get there first then actively kill off every competitior that they could. Facebook doesn't actually DO anything new or provide any unique service. The tech isn't really theirs. It's easily replaced. Shut it down.
I’m sorry, but there’s just no affirmative case for this company to exist. I get it, groups have used and still use Facebook to organize, etc, but the inherent terribleness of this organization necessitates closing it down completely.
