Purchasing the company (and/or the product) doesn't necessarily mean they're bringing it fully under the Facebook system, I guess. But you'd have to expect they're gonna want a little 'link activity to my facebook account' button. The long and short of it is, Occulus Rift is going to make money, period, and Facebook wants that money. Now, they're firmly invested in 'not ruining the Occulus Rift,' so at the end of the day, I really doubt they're going to flood it with unwanted social bullshit. That wouldn't make sense to do -- hurting both the 'facebook' side with bad press, and the Occulus side with annoying popups. Companies don't make money by making bad decisions..... but, we'll see. I'm pretty sure it's gonna be fine though, in the end.
