I think you bring up some good points of open source projects vs. commercial ones. In open source projects, most of the time when seeing critical feedback by users you see those "it's open source, just change it the way you want" comments. No one makes money, therefore no one depends on users being happy about the software. That's why B2B is so attractive: Your users actually WANT to pay you such that you are dependent on their happiness. Maybe we should invent a new model that combines open source with paid incentives for user desired changes. Let's say User A uses Gimp, sees something that could be simplified or added. He can't program it himself but what he can do is describing the feature he wants, possibly with screenshots or even an interface prototype. He then auctions this on a marketplace website. Other users can upvote or even chip in to A's auction such that the probability of a good developer implementing it rises. Developers have their profile with reputation, possibly linked with their stackoverflow reputation. The change gets implemented within a branch of gimp, installable by anyone using a modified package manager. If the maintainers of gimp like the change, they can merge it in such that everyone profits - the number of user downloads being a good indicator that the change is desired.
