What do people that have contributed to the code base get? Who is getting money for this? I don't understand how you can go from an opensource project to a for-profit project.
With open source you let people use your code, and they let others - including you - use their code in turn. That's the payment, if you will. If you contributed to CM, then the availability of the rest of the CM codebase under a compatible license is what you get.
As for profits - nothing stops you from taking the rest of the CM code base and trying to make it a business, in the same way the CM devels are doing now. And if you do, you won't have to pay the CM developers (or the kernel devels, or user-space tool developers and so on) any more than they have to pay you.
