Companies like Microsoft, Google, and Facebook are huge open source contributors specifically bc they can get a return on their investment. While your intentions may be noble, I think you'll find that more restrictive licenses will have the exact opposite effect and open source projects and contributions will be quickly whither and die. Open source was never about preventing people from making money on the works they create, it is about preventing companies from telling people what they can and can't do with that code. It is about insuring forward progress and the ability to build on what other people do, making it better, and ensuring that that future is not meddled with. Or restricted. And there are plenty of licenses that accomplish that, the GPL and it's offshoots chief among them.
