My "fear" has always been that Meta/Alphabet would slowly but surely migrate their apps over to their own third-party App Store to get past the pesky IDFA limitations[0] and other tracking hurdles.

So far nothing seems to indicate that it's happening. The question is if it's due to Apple's "measures" or just because it is not worthwhile for Meta/Alphabet. I think it's a combination of. But if it was as easy to "side-load" an app on iOS as on macOS - per your suggestion, I'm confident Meta would have done the switch in a heartbeat.

Just imagine if Apple provided nice API's for auto-updating, essentially no limitations on what binaries can be attested, API's/mechanisms for easy migration between AppStore apps and side loaded ones, no scary screens etc. Essentially implementing the DMA to the fullest extent, really honouring the intent of the law. Why wouldn't all the mega apps just move over? And what consequences would it have?

I think it would be awesome to e.g lift the JIT blocking and allow more strange niche things in alternative app stores. But getting all regular people on a wild-west third party app stores for the (ad financed) apps the use every day is just begging for a huge _actual_ loss in privacy.

I think it's just not worth it for them; look at Android, where sideloading was always available as an option.

Facebook does offer separate APKs on their website (so do, in fact, most major services - Netflix and Spotify also offer APKs from their website), but practically the only reason people end up using them is if they're on a device that doesn't support the Play Store (for whatever reason).

The only serious Play Store competitors on Android are either vendor specific (like Amazon's store) or wouldn't host Facebook apps to begin with and are unambiguously a positive force for users due to their standards (F-Droid, whose policies are designed to protect users from the typical mobile app rugpull of filling it with ads down the line). Anything outside of this tends to be independent hobby projects or corporate business apps.

The inertia of being the default is still really strong (for a slight alternative, much of Google's strength comes from the fact they paid millions to browsers to be the default search engine for them, a practice that's been found to have violated antitrust laws - it's telling that Google really wanted to keep doing this), which is still enough to keep Facebook attached to the Play Store and is probably why they won't try to leave the App Store either.
