I’ll start: I use iOS primarily since iPhones don’t have custom ROMs

It’s much more correct to say that Lineage or Graphene are Android than saying that Android is Linux.

Both of these are correct. LineageOS and GrapheneOS are AOSP; AOSP is Linux.

Linux is a kernel. Other components must be added onto Linux to create a complete Linux operating system. Adding stuff onto Linux does not subtract any Linuxness from it. Any Linux OS is "real Linux." Saying that some Linuxes are not real Linux is like saying if you add peanut butter to bread you no longer have "real bread." It is nonsense.

I was not precise. I should have said gnu-Linux to differentiate from Linux as just the kernel, my bad. It's gnu-libux that gives you that feel you are on the family even if you have ubuntu or Gentoo.

But I beg to differ: AOSP cannot be called Linux in any way. It happens to use Linux as a kernel as you say, but lacks everything that make an SO typically Linux(or gnu-linux):

starting from the base of the system, AOSP doesn't use libc s system library like gnu-Linux
even the C++ STD library of AOSP is incompatible as it lacks RTTI
doesn't use anything like systemd or the init system (unless mod-added)
has a totally different HAL which is not compatible between the two
has a totally different network tooling stack
has a totally incompatible GUI layer
Most of android drivers have a thin kernel layer plus a huge proprietary AOSP layer libraries which are not gnu-Linux compatible
the entire ecosystem of AOSP is kotlin/JavaScript instead of just being language agnostic

So no, you cannot say at all that AOSP is Linux after all. While you can run gnu-Linux binaries on android, and viceversa, you must provide a complete environment around them, like termux. It's more a container like approach.

They only share a kernel and there have been plans to replace that too.
