This is a behavior that really pisses of the community and although they state otherwise, Ubuntu would cease to exist without that community. Basically they cutted one of their legs because their head thinks "Hey, I am up here, what do I need legs for?" This will seriously backfire for Canonical, as you can see that more and more community projects simply don't want to support them anymore.
Ubuntu wasnít going to take my patches because they donít want to take community patches on compiz anymore.
