They only can (try to) dictate to others and make them do what they want and need. Which is hardly making Linux any better, I think.
Basically I wanted to say that Ubuntu may or may not have succeeded in getting a large developer following, but it surely has developed a healthy and active community and not just a passive userbase.
Like Microsoft directing all search to Windows Live, or the iPhone using the iTunes Music Store? The difference is that Ubuntu is at least cost-free.
The reality is that nobody cares about this. Those that do should be using Debian. (The only value that Ubuntu has added is a default color scheme and nice desktop background for Gnome. Most Linux users have not gotten much from Ubuntu.)
