Let me take your imagination to a (short) trip: You can build a pretty decent psychological profile from a 30-50h game-play(even less if you design your game with this type of user-data in mind); this alone has HUGE implications(and possible use-cases) I won't go into.. If you combine the data from ALL VR EXPERIENCES through facebooks rift(and let me stress this again - we're talking about most of today's entertainment industry(+education), data the media has been dreaming of for years).. Even if eye-tracking won't be implemented, your VR interactions become a very neat addition to all the data - facebook alone - is gathering already - marketable like nothing before. As someone already mentioned here, being the first on the market means(among other things) that I as a potential VR customer won't really have options to choose from - my options are FB's rift, Sony's PS4+VR combo or just to wait for another ~5 years till enough VR parts are lying around so the smaller companies can have a go(although one may still not be able to watch the 360 F1 driver camera "facebook experience" feed from a "asus vr" kit). I'm fully aware that if most of my family/friends/colleagues/whatnot are on fb, it doesn't really matter if I'm using fb or not - data-wise(don't worry - till you are demonstrating in front of the "right" embassy, all is OK .. for now) - but this is a whole new attack vector for privacy.. and propaganda. If media are the only unregulated weapon of mass destruction on the planet, what is VR in hands of facebook then?
