"The vision of Bitcoin is that it isn't any single person's vision" - that is the real problem with Bitcoin, which is why we have so many forks. Open-source development can be sometimes faster given there is a strong, and intelligent leadership that encourages innovation and cares about users. Forks do happen in open-source software development, but not that many. Linux is innovative and fast moving, it has been only growing in popularity and there is only a single popular fork - Android.
