The European Commission Versus Android Stratechery By Ben Thompson
This is a great overview of the EU’s decision against Google and Android. Google has been strong arming OEMs for years and locking more and more of the Android OS down.
If Android were truly open source, I’d expect to see many more forks than we have today, but Google makes sure that doesn’t happen by moving more and more into Google Play Services and letting those pieces of the Android Open Source project languish.
