The Open Source Community’s strength has always been in its numbers and the will of developers contributing to projects to drive project initiatives in the direction they desire simply by voting with their time and willingness to contribute. If a project no longer meets their requirements, be it from a licensing or political perspective, they simply cease working on it and go onto other things that interest them instead.
That is the beauty of of Open Source, in that it is pure Social Darwinism and Software Phylogenetics at work. Even if you have a bunch of large natural predators, such as Constrictus Siliconvallis, it’s not possible for them to swallow entire communities, even if they buy the companies that run the projects themselves. And like evolutionary trees, if projects are to be compared to Phyla, they do indeed branch off.
