By the way, is there a phrase besides [company] world? I only used it because I couldn't think of a term at the time.
Platform and its ecosystem.
Linux's greatest enemy is its own community. Biggest improvements have originated from companies, such as Red Hat, Canonical, Novell, SuSe, etc and not from the individuals of the community. Of course there are exceptions, people who have contributed majorly to Linux outside of their employment. Apt comparison of Linux community at personal level would be a big family full of talented children but no adults. Children who always fight and have tantrums.
No doubt a community can work together, as evidenced by Debian. One of the oldest and popular distros now. But even Debian has had its fair share of trouble from its own supporting community. I believe charismatic and capable leader personalities have strong impact on the community and can make it work better. Unfortunately such personalities are extremely rare in the Linux community, they're less about being charismatic leaders and more about bolstering their own ego and generally being dicks.

I don't really know much about Shuttleworth's personality, but at least he has made Ubuntu a huge success at the expense of his own financials. You see, as far as I know Ubuntu has not made profit like ever (yet). But the more popular it becomes, the more people and particularly companies opt to buy their supporting services, thus generating income and paving road to further improvements that benefit the Linux community, despite people complaining about lack of upstream contribution.
I can't but wonder what kind of impact will SteamOS have. Can't wait to try it out.
And meanwhile, you can keep your eyes out on Firefox OS for phones.
