> Can you name an OS that gives more support to OEMs than Android?

I don't see how this is relevant for this discussion? The whole point is that Android is only opensource in name. You must license Google Play services from Google otherwise Android is practically useless since you can't run 99.9% of the Android apps. When you license Google Play services Google will also impose all kinds of other restrictions on you which have nothing to do with Google Play services. Like for example mandating you don't set Perplexity AI as the default...

Imagine Microsoft "open-sourcing" Windows (by doing some source drops at regular intervals) but you wouldn't be able to run all the existing Windows applications on it without licensing closed source software and online services from Microsoft.

Windows Phone, before Android and iOS killed it.

Incidentally, version 8 was vastly superior to current iOS or Android, even after those OS’s stole a few UI innovations.

If only the team responsible for that got to run Windows, and not the other way around!
