I agree with this. We would also have more competition because other players in the space wouldn't be as intimidated to go up against a business like Meta/Facebook.
I think a crucial miscalculation was trying to EEE the space. Zuck clearly states that he wanted Meta to "own the space" on every platform. Basically, he wanted to carve out a niche like Adobe managed to do with PDF, but on a scale that rivals full blown platforms like the Android ecosystem. Such an ambitious plan sounds great on paper, until you realize that you're trying to EEE the exact people who wrote the textbooks on EEE. When you sound a horn that loud, on a megaphone as big as the one Meta was using, you're only painting a target on your own back.
Another drawback to the path that Meta selected is they basically internalized the entire hardware industry that was just starting up. If Oculus had stayed independent I believe they would have had to partner with other hardware vendors to establish some sort of regulatory body for writing industry standard specifications. With one serious player in the field developing and harboring all the tech for themselves, this space could be barren for a long time if Meta folds. All the work by third parties that went into this proprietary technology and platform will basically be for nothing.
