@Suzu @Humpleupagus @anonymous @Zergling_man there does. in many cases some flavor of linux will run, and in nearly all cases android will run. android is a "real os" it just ships in a state that locks the user out

the issues are stuff like shitty embedded style firmware, shitty NDAs covering component specs, shitty driver support (see previous point), being locked out of the secure boot implementation, being forced to deal with the shitty android verified boot thing that sits on top of the secure boot implementation (which you are usually also locked out of), the general nightmare involved with trying to modify, rebuild, and deploy pieces of android proper (as opposed to "apps"), and probably some other stuff that I'm forgetting off the top of my head
