I think it's better and worse in slightly different ways. On the one hand, yeah a Chromebook won't let you touch the default OS without switching to developer mode, and won't let you install a new OS without disabling the write-protect screw or firmware option. On the other hand, every ChromeOS device allows you to do exactly that, and then you can run whatever you want and you should have at least some support for upstream Linux because ChromeOS upstreams their drivers. (I will happily agree that the Android device situation is awful.)

By what definition is PMOS not a "full" distro? It's Alpine plus some extra stuff, including device tweaks and out-of-the-box desktop environments.
