When you say someone is "being fucked" by an open-source project I see that as the project itself, or the people on the project, causing a significant problem for the person involved. In fact, I would say that such a strong term means that the the detrimental aspect is likely intentional. The project itself is causing a negative action to that person. This is not what I'm describing.
When I say the response is "fuck you with a smile", there's no detrimental action involved. I see it as a very impolite way of saying no. The person receiving the response can ignore it or choose to go somewhere else, either way there's no real negative action being done to them. All I'm saying is with that response I would assume most people would choose to go somewhere else.
Again, this issue isn't whether someone acts with a sense of entitlement if they complain that their suggestion or bug report isn't implemented. As I said before, if someone whines in that instance then the problem is with them, not the developers. On the other hand, if someone makes a statement along the lines of "this feature doesn't seem to work right", or "this bug prevents me from doing something I want to do", or "it would be nice if this feature was implemented" then responses like "only contributors can complain!" or "learn to code and fix it yourself!" are developers using the "fuck you with a smile" response. I feel that is wrong and not productive in any way. It is actions like this that will push people away from the idea of open-source software because who wants to deal with that nonsense?
