Facebook is very valuable in countries where press freedom is not good (if facebook is not blocked yet). My country (Azerbaijan) is one of the worst countries in terms of press freedom. The only “free press” we have is a facebook. There are many goverment’s trolls, but everybody understands when trolls write something (trolls get average salary). On the other hand, goverment follows oppositions’ discussions on facebook and responds accordingly. That is the only platform we have now goverment and oppositions speak with each other.
Facebook is about looking at hot girls from your college, well, that's how it started out. It's a social network where you and your data are the product. It's not about free press.
If we act based on this logic, then we should not use internet today, because it started as a military project. Well the telephone was created as a tool to talk each other not to browse on the internet. We can add many examples that initial usage changed significantly.
Just because it played a part in those events doesn't mean that it's not a tool for free press. One could argue that the fact that that speech wasn't able to be passed through traditional media is a point in favor of free speech, even if it resulted in violence.
