@kevin@social.interlunium.nl What are these "some AOSP-derived OS's" you refer to? And what is their functionality compared to SailfishOS in daily drive for regular people as alternative? What do you think? I suppose you can only research (via other people near you or so) as you don't own or use anything what is being discussed here. As said - SailfishOS is already ~95% open source / the main part remaining is the Silica UI (graphical user interface).
