I feel conflicted here. I try to give people the benefit of the doubt by educating them a bit and explaining up front what funds the project as well as what the scope is.
As a maintainer, seeing it every does tend to annoy me a bit. I always try to remind myself people dont usually mean ill though. All bets are off if people continue to disregard the framework for engagement though.
Most people are a bit surprised I do this but are generally receptive after the initial explanation.
My main philosophy in these interactions is just to treat people professionally while being stern on things out of scope.
