We have mobile Linux. It's only supported on less than a dozen handsets and runs like shit, but we have it already. The reason nobody uses mobile Linux is that it has to compete with AOSP-derived OSes like LineageOS and GrapheneOS, which don't suck or run like shit. This is what it looks like when people vote with their dollars, people want the status-quo we have (despite the horrible economic damages).
