While the story is Palmer founded Oculus (and he was the original founder, so there is truth there), really Brendan Iribe, Michael Antonov and Nate Mitchell (Scaleform Mafia, all serial founders) negotiated the Facebook acquisition. Palmer was pushed out first after acquisition. He's a nice marketing story (nerdy young white boy reinvents VR) but he wasn't the driving force behind the business success (Brendan and Nate) or technical success (Carmack, Antonov, Abrash and many others like Dean Beeler and Volga Askoy).
We're also in a world where all the founders of Oculus have quit and no longer have a say in decisions like this. Facebook foundational employees and recent hires are running the show and the end game for Oculus is to give Facebook a platform that they control that is as pervasive as iOS or Android (or at least Xbox or PlayStation).
As a former Oculus and Facebook employee I'm torn by this. I always understood how a none trivial portion of the Oculus user base is extremely anti-Facebook, or even how people with Facebook accounts didn't want their Facebook account tied to Oculus. At the same time it would seriously reduce technical friction around using Facebook backend features in Oculus products. I know some folks would see this as a complete negative and I understand where you are coming from, but there are some interesting positive use cases as well.
