When a user uses some open source software, there is no negative happening. They are not accumulating some debt that should be repaid by "contributing back." If they make a million dollars on it, that makes no difference to the project. Agreeing to a license and then following that license is not "bad faith."

The only damage being done when someone makes money using open source software, is to the ambitions and ego of a developer who imagined that "open source" meant "give me your contributions so I can build an empire." Fortunately, open source is for the benefit of all of us. Nobody owes them fiefs.
