Honest question, do you have anything to base this idea that of "many many more times the resources" on? Have any companies been acquired by FB and immediately gone about pushing the envelope in ways that don't strictly line up the existing business of FB?
I think the concern here is entirely justified.
The Rift is a breakthrough product made possible by people who believed enough to back it via Kickstarter. Once delivered the community set about creating a whole range of wild stuff and general made those creations freely available.
Nobody wants to see their creativity hindered by some new corporate developer standards or restricted to distribution through something that sits behind a Facebook login.
Personally, I want the Rift to let me walk on the surface of the sun not allow me the privilege of paying a Facbook/NBA partnership for artificially scarce virtual "courtside" seats to a game.
