Being a commercial Linux distribution editor is tough.
There are a few commercial Linux distribution editors in the world: Red Hat, Novell/Suse, Turbolinux, Mandriva, Ubuntu/Canonical, Linspire, Xandros, Red Flag, CS2C and Sun Wah to name the key ones.
Yes, yes, I do put Ubuntu/Canonical in the list (what a blasphemy) and will elaborate in a further post on why I do so. Of course, I do not put Debian in there, which is a true community based non commercial distribution.
To my knowledge, the only companies in that list which actually publish their financial numbers are Red Hat, Turbolinux and Mandriva.
Further to my knowledge, the only company making money is Red Hat.
