I like the walled garden but its a bit of an exaggeration to say they are doing a good job.

Just last week, while looking for a password app, they had a "validator" app with in-app purchases using the old google authenticator logo in the #1 position. Worse it was an ad; someone saw all of that, both as an ad and as an app, and let it go.

>Quite naive take, you don't have to use any of your examples to deploy to Android, Windows, Linux or MacOS. It would be more like Microsoft charging a per-install fee on using the Win32 APIs which sounds outrageous.

"sounds outrageous" is a pretty weak justification for regulator action. Paying for a browser probably sounds equally as outrageous, but with the way anti-trust is going with Chrome/Google, that seems like a very real possibility. Moreover, why should the government should be in the basis of regulating business models? If Apple wants to charge for access to its SDKs, and it pays the price through less apps for its users, so be it.
