These things are being made by people mostly for free. I know there's corporate funding and donations amongst bigger projects, but they're being made by people, for free, so that a free alternative to expensive software can exist. It's one thing to complain about software you pay for negatively. When I used alphaCAM and Park Industry software I expected to be able to phone them any time and they'd hop on TeamViewer and help me with any and every minor problem, but alphaCAM costs $10,000/year. For that $10,000/year i have every right to complain or ask for any bit of customer service I want, for $0/Ever, I can deal with it, make a polite suggestion and hope for the best, or submit a patch.
