> it's already free software

I'd just like to interject here for a moment. The word Free Software has a specific meaning that AOSP does not meet. The only component of AOSF that is Free Software is the Kernel, due to GPL, and aside from low-level Android-specific modules such as binder there's no secret sauce in Android kernels; even the vendor modifications are mostly gutted out in favour of Project Treble and GKI. Everything else is only Open Source and not Free Software, and even then developed privately and only published upon release. Because nobody releases a pure AOSP phone (Google Play Services alone changes the OS behaviour dramatically, punching through all the usual app sandboxes) and the source code for the modification, it's effectively proprietary with open source components.
