I don’t really visit FOSS communities, however I have given my fair share of bug reports and feedback. (I’m a game programmer)
Most communities welcome the feedback. I know I can be blunt, or even out of line while reporting sometimes. I try to be the “asshole” before another person comes along without my experience who actually is an asshole and doesn’t know what they’re talking about.
It’s also a minor test to see how they respond to rough feedback. I don’t think anyone has mishandled it so far. They are always polite and respectful to customers, and I usually relax after the first encounter.
I try to make it clear that the feedback I give has importance (when i know what im talking about), or if its minor, i tell them its not a real issue, not worth fixing, etc. If they reject it, it stops there. More often than not, they are understanding.
I don’t recall any blatant arrogance in any responses so far.
