I think the larger dev ecosystem has created a bit of backlash against the big players for some time and aren't quick to adopt the new tech they are dishing out. I would guess taking a 30% cut, lawsuits, and unfair terms has left a sour taste in everyone's mouth.
And it wasn't until competition stepped up with an indie dev, aka a YouTube VR app called Juno made for the Vision Pro, that even Google decided to jump into developing YouTube for the Vision Pro.
So now we are back at the chicken and the egg problem and few big devs want to support the giants. It'll happen probably eventually when monetization becomes a reality for devs embracing the tech but I don't see it happening any time soon.
