If you make your project open source, your goal should be maximizing people using it,
not maximizing how much you profit from it. I know they may seem identical, but they aren't: Apple makes a lot of money by making software that has huge roadblocks to using it. And as many people are now realizing, open source has the ability to
not make lots of money by making it incredibly easy for anyone to use.
We all benefit greatly from Linux, and I think most people have not contributed back to it in any meaningful way, monetary or otherwise. A lot of these projects only exist because they were built on top of other Open Source solutions with no expectation to give them any sort of "cut". Had Linus decided he actually wanted to start a hardware business and then got angry that IBM was better at putting Linux on metal than he was, it would be similar to this situation and I think most of us would be unhappy about a bunch of turmoil resulting from that. But when it's someone else's ideas that are being used for free, they always seem obvious and fundamental, when its your own, it's unique and unfair.
As others have said here, it is OK to say "wait a minute, I want something different", and then do something different. What is not OK is wanting to water down the definition of the term open source so that whatever thing you want to do still gets to use it. The OSI's position here is perfectly reasonable -- that doesn't mean you can't invent some new kind of license or relationship. People forget that OSI had to work to get into industry in the first place, it wasn't automatically accepted. It is somewhat funny and ironic that others now want to benefit from this work while doing something completely different.
