This certainly came out of left field but after reading the press release I can *sorta* see why Facebook would want it.

It's good Sony stepped up to compete with them but Oculus was going to fill that open source niche, where eventually, anyone can accessibly showcase and consume content for it via Steam. As long as this deal doesn't hinder that trajectory I don't think it'll be anything to worry about. But personally I'm not too emotionally invested in VR right now. I'm fine with my screens.
