Comment 1292 for bug 1

Promoting Ubuntu is the least of the problems. Money is needed to engineer the system in the fist place. Some people have mentioned Apple and that is a good example. Apple controls and finances OS X because they have a business model to support it. Perhaps that's why OS X is a nice, usable operating system that people actually do want to use and Ubuntu is not.

You also may notice that Apple does not release a new version of OS X every 6 months to keep applications "fresh". Maybe they don't need it because they consider each release to be a stable platform that ISVs and IHVs can target?
