I can get the source of the kernel, including all drivers, running on my android phone with a few clicks and build a custom ROM.

Where can I get the source of the exact kernel running on iOS devices, including all drivers?

How about the Playstation 4 or 5? Where can I get the source of their FreeBSD fork?

No, most drivers are closed source and you can just extract binary blobs for them. They run as daemons that communicate through the binder ipc - Android basically turned the Linux kernel into a microkernel.

Indeed, since Android 8 all drivers are in userspace and use Android IPC to talk to the Linux kernel.

Traditional Linux drivers are considered legacy in Android.

Yep, my Pixel 5 with stock OS and Pixel 6 with Graphene are hacked via WiFi blobs, which are not updated and cannot be patched.
