These operating systems aren't compatible with most of the apps and services people want to use. It's going to become much worse. The compatibility layers several provide have extremely poor compatibility combined with disabling the Android security model and app sandbox. Apps running in those compatibility layers are much less contained with less isolation from the Linux kernel, not more.
Aside from that, many people care about privacy and security. Each of those operating systems is far less private and drastically less secure than the Android Open Source Project. None has a truly complete and working app sandbox or permission model. None uses modern exploit protections. None has serious hardware-based encryption features needed to protect against data extraction. They're not serious alternatives to an iPhone from a privacy and security perspective as an AOSP-based OS on decent hardware can be.

It's a warning that's being added to Google Mobile Services operating systems. It doesn't negatively impact other operating systems based on the Android Open Source Project.

Linux doesn't mean GNU/Linux or systemd/Linux. It doesn't at all imply using glibc, systemd, GNU coreutils, Bash, GNOME, etc. Distributions using different userspace components including several of the ones you've listed are still Linux Android-based operating systems including AOSP and GrapheneOS are Linux distributions. Alpine doesn't use glibc and SailfishOS has a lot of their own mix of open and closed source software. Using a typical desktop Linux userspace stack isn't what makes it Linux and there's also not a lot of consistency in what's used on desktops regardless. A Linux distribution not using musl, glibc, GNU coreutils, etc. is still Linux.

AOSP-based mobile operating systems are Linux distributions.
"Apps running in those compatibility layers are much less contained with less isolation from the Linux kernel, not more."
Being isolated a little bit more from the kernal offers an illusion of privacy meanwhile where you are, what you have installed, your photos and friends are available to other apps at a much higher level. I understand being able to slow down a nation state actor is important but most privacy concerns for average people happen at the OS level not the kernel.
This claim is false. Isolation and protection from the kernel is vital and it is already targeted for exploitation, and will be targeted even more as time goes on. Properly updating the kernel and improving its isolation and security is the bare minimum for even below average users, not just for high threat models. The claims you are making are unsubstantiated.

Exactly this.
If I can't run WeChat, Venmo, my brokerage app, WhatsApp, etc. it's a non-starter for me. I might as well not have a phone, because these apps are pretty much the only reason I carry around a phone.
