I'm not a fan of Facebooks policies in general, but Facebooks future application of the device is simply likely to be at the forefront of the future market and providing exclusive telepresence software;
I didn't get in on the ground floor with Oculus to get first crack at telepresence software, I got in to play games! Which is why I say fuck this!
And there is absolutely nothing making the two mutually exclusive.
Oculus is a hardware company, they will continue to focus on making a nice piece of hardware which by their repeated statements, both pre and post Facebook buyout, would have a gaming first focus. Facebook is a software company, they'll make whatever software makes sense for them to make for it, and push the Rift vs other VR headsets as their preferred platform on that software.
Just because you (rhetorically) run a Windows computer doesn't mean your computer is best suited to, or only capable of, running Microsoft Word.
And for the record I own a DK1 and have preorded a DK2, I am no less in on the ground floor with Oculus.
It does mean, however, that oculus' focus is no longer on just providing an outstanding gaming experience.
