Being a developer myself and having done many free and paid projects for people around here and litecoin, I think the issue is that this "help" is generating you income...why wouldn't you pay for it? Im not directing this at you per say, but I don't think the devs are the ones that are greedy, but everyone else that is making money off our work, and get very little in return, especially when we help out the community and put our stuff out there for free.

Of course there are greedy devs too, especially the ones that use their skills to scam people, but thats another discussion. I think people would get a lot more out of things if more people donated to stuff that people put out for free, and they would be more inclined to fix/improve stuff instead of not caring.
