Just another guy abandoning the old internet.
IRIX was Unix based with BSD extensions and I believe Maxx Interactive now runs on FreeBSD without Linux compatibility mode. So hopefully it won’t be long before it goes open source. Though I can’t understand why it would be needed outside of anything but nostalgia.
Android? It’s not wholly closed source similar to RedHat they’ve got closed source elements while using open source elements.
Linux and its kernel are based on GPL and so to distribute something using it would require a compatible license. That means a full distro can’t be anything but open source and actually be distributed in free or paid versions. That doesn’t mean there aren’t closed source interfaces being used personally or undistributed.
Oof Sourceforge AND flatpaks? I’ll have to check this out but I’ll make sure I read it over well before anything.
