Well, Facebook and Google goals align (gather as much user data as possible) so that is probably the reason. FB literally took print ads to try to fight the tracking disclosure tags Apple wants them to use, so yeah, I can see FB probably having their own app store on day 1 the moment iOS allows it

Because on Android, Google doesn’t give a crap about privacy and Facebook knows it, so they’re quite happy to stay on the Play Store.

The same goes for a ton of other apps, they’d all swing over up a ‘Freedom Store’ on iOS. They don’t need up do that on Android because Google.

To quote the parent commenter:

> I don’t want Facebook, Google, Amazon, etc to be able to do an end run around App Store controls.

Alternative stores is a subset of this core issue: sideloading apps to circumvent the gatekeeping process that Apple created for the users benefit.
