I actually use gnome 3, and I'd hate to see it gone. I think even with its problems, its the future.
Sure they made some bad decisions.
Good it works for you. I don't know if your last paragraph referred to the OPW or the UI. I don't really have strong opinions one way or the other about their getting involved with the OPW, but to me the main bad decision was that they essentially made Gnome 3 into something completely different, while removing as many features as possible. Many people, including me, used Gnome because they basically liked how it worked. The current Gnome 3 should have been a fork, which could very well have been managed by the same people. They could have sanctioned that the current Mate devs managed *their* version, still under the Gnome umbrella.
Their attitude when confronted with the reality of the majority of users' opinions certainly don't garner much sympathy from me, either. If they had acted in a different manner, and certainly if they had gotten rid of their attitude, they would have had many more supporters now when they're in financial straits.
