This person isn't doing anything wrong. He's appealing to what he perceives as universal principles to attract attention to a technical matter of importance to him. Yes, he's being aggressive; no, there's nothing wrong with that.
If you take away the voices of such people, pretty much the only voice left speaking is the voice of corporate money, which is usually anthithetical to the principles of open source development.
EDIT: Especially considering features like Gopher and MSP were deemed worthy of attention, the fact that his point about HDR metadata being silently stripped was not being addressed in a year is concerning.

Being an asshole is bad, specially when you are asking for help. Not being an asshole doesn't make you a corporate shill nor being an asshole make your feedback "better".
