Yeah, this is a non-trivial effect. It affects FreeCAD too. Mostly contained to the forums, but if you ask a question it's wise to give people who actually know what they're talking about a couple of days to show up.
I think part of it is also the user knowing that they have no right to express frustration when the product is free. That's actually a mental burden. In a sense, people buy software partly so they feel they have the right to complain when it has issues. And honestly I think that's pretty reasonable
No, they do have the right to express frustration. What they don't have is the right to demand work from anyone else, but what tends to happen is that communities are on such a hair trigger for the latter that they reject the former even when the frustration is directly caused by a solvable problem.
