Meta likely has the most apps and most users of any one VR platform. Sure everyone needs apps, but they needs apps the least, especially from Play Store.
Unless you see using phone apps as 90" virtual screens as a killer feature at least.
(Android was like a year later)
Same fate can happen to metaverse - someone can make a better VR platform.
Doesnt help them that what they have is shit.
As a user you can already sideload android APKs, I've tried it works great, but you also need to install apps that manage android permissions since you can't grant them through the quest settings.
having the android store there + integrations where android app devs can make the app VR ready would be a big plus. But, the blocker is that google still has ambitions of making some sort of big comeback on the android VR space and therefore are in direct competition with meta.
