Facebook is a jewish invention among other things. It's not haram to use it, so long as you're not using it to commit sins obviously. It's not in the deen of Islam to avoid an invention because the kuffar made it. As a matter of fact it's permissible also as ghanimah. Their inventions, their wealth is encouragement for us to fight jihad and take them as war booty.

I myself didn't take the shot because I think they're trying way too hard to censor any reasonable opposition to it which really doesn't make them look credible but to say it's haram is speaking on behalf of Allah with no evidence.
