Imagine having the most famous open source project using your product for the world to see and losing all that free publicity in a desperate attempt for control.
The sad part is that BitKeeper really was an amazing product and way ahead of its time, pioneering many of the features git later made popular. Had they just been a bit smarter about the whole thing they could be where git (and GitHub) is today
Ironically the last thing they did before going bankrupt was release BitKeeper as Open Source.
But he lost the opportunity to remain central to the booming FOSS ecosystem, and all that it entails.
