For now. I do not expect Meta will allow headsets indefinite multi-source operability. At some point they will force a rift between first party and third party games, but not until they’ve truly starved major competition out.
I think that is the trade off for higher than average salaries and one heck of a foot in the (tech) door. I do have a friend working there now, he seems mostly content with it. I doubt he’ll be switching anytime soon.
