It sounds like an open source e-book that you have to pay to "develop" for. Great idea in general, but although i don't mind doing work for free, i mind others

It sounds like an open source e-book that you have to pay to "develop" for. Great idea in general, but although i don't mind doing work for free, i mind others getting paid for it instead of me. If they incorporate some sort of payment system, so that part of the revenue goes to contributors it might be a different story.
