Yes, yes, I realize Ubuntu is not a company at all but a free Linux distribution, GPL'd and open source by definition. But still, the Ubuntu distro is sponsored by a traditional for profit company, Canonical Ltd, and it is very fair to say that the distro would not exist without the company. Ubuntu describes itself on its web site as "a community developed and supported project," but in reality it has no separate existence from Canonical and that firm's owner and founder Mark Shuttleworth
