My guess: The simple answer is they want to be the VR platform of the future so they can show ads on it, however that may look. Selling ads in VR apps/games/homescreen is obvious - selling AR ads is probably on the horizon (so, if you look at your fridge in the Oculus Quest 5 AR you'll see an ad asking you to upgrade to the latest Samsung Fridge).
I kind of doubt we have anything to worry about now, but there is a terrifying future on the horizon where everything you look at, everything you do, is measured and any value is extracted and sent to ~~our new overlords~~ FB.
