Well, many people invested their spare time in Maemo and they did that for the community as well.
Seeing some community members complaining about their effort in a non rationale way, would bother me as well.
I wouldn't care and let it go, as surely they are not understanding not even a fraction of what these people did and are doing (otherwise, hopefully, they would have been more polite) and how.

But it hurts. And it shouldn't be like that.
