I'm not gonna say forking is always the answer, or that it doesn't sometimes suck for the project as a whole when some people go one direction and some people go another, but I'm inclined to agree with the spirit of your comment that the ability to do so is a feature of OSS, not a bug.

This is a blog post written from one side (and a side I'm generally more sympathetic to) but no doubt when it is a major break between two factions, especially "founders" versus "maintainers" there are obviously two sides to the story, and the great thing is that one side doesn't always have to "win"
