Mandatory meta/fb account which i am very glad to have gotten rid off some time before that.

Not like i trust the Chinese for not spying but they are less likely to be interested in my data as opposed to chinese people living in the west.

Also did i mention apk support. Not sure if quest does. This thing can do piracy digital archiving , got moded beat saber working on device and officially its not even supported Hardware.

Another reason was bigger FOV but i am not about the latest quest in comparison.
