@JoshuaACNewman@zleap@Jennifer It's true, there are at least as many jerks writing FOSS as in the rest of the population and many are grumpy about the stream of suggestions, requests, and demands that come in for even mildly popular projects.
That said, my experience with closed software has been aggressively user hostile at best. Mastercam won't even notice small fries like me but the FreeCAD team has been awesome.
