I will never contribute to their goddamn projects. I'll either do my own shit or just keep working for a company. Everyone needs to think hard if they really want to develop software for free for such an ungrateful community that will stab them in the back. Making a project open source has so many advantages but if you can't trust the people you're working with anymore, then there will be nothing left of it other than a race for gaining the most control in a given project.
