Facebook has a pretty good record of non-interference with acquisitions, especially in the user-facing sense that you're describing. It will be even more true for Oculus, because Oculus was not a competitor to Facebook like Instagram, and, to a lesser extent, WhatsApp.
Facebook buying Oculus was a two-billion dollar bet on virtual reality being the next big platform, and to have that bet pay off, Facebook has to play the long game, and let Oculus and the virtual reality market grow.
Facebook isn't stupid or myopic enough to require a Facebook login to use Oculus products. It makes absolutely no sense when you consider the reasons that Facebook bought Oculus.
Why not? That's a very strong statement. I could think of a countless number of bets that trivially match your criteria (i.e. even odds Facebook will not stop selling ads this year), that you'd be crazy not to take.
There are lots of reasons. But I looked at your comment history and decided not to jump on the "interpreting discussion threads as logic statements" train with you. Apologies.
