I had heard the “PosmarketOS” name in the past but it never sparked my interest, I had always assumed it was an OS made for some old obscure hardware that I’m likely to not own or that I would not be able to buy anymore. Either that, or a distro meant for old PCs.

I just found out that it comes shipped in PinePhones.

I wouldn’t say I really care if the “community” is big or small (it’s also a bit unclear what you mean exactly, do you just mean user adoption?)… but I care about Linux (and in general, open source alternatives) being real options when it comes to hardware support, compatibility with services I might want to use, etc.

I don’t think you can have proper “progress” in those areas without having Linux be a recognized mainstream system. Like say… banks are unlikely to make an authenticator app for non-Android Linux phones if non-Android Linux phones are not mainstream, for example.
