From the FAQ: > Open source is public source that's monetarily free This isn't really true, as you really can charge for free software as much as you want, but you also can't forbid people from redistributing it without paying for it. This is why you can't download from RedHat's repos without paying for access, but also why CentOS can exist. (I have also heard that RedHat threatens to terminate your access if you exercise your redistribution rights, but I am not sure this is true.) I guess "supported source" is a statement that there is only room for one Red Hat in this world, and everyone else must restrict redistribution.
