I had a GitHub project that got a few hundred stars. The amount of mean, crazy, and entitled people is crazy. I have no idea how the bigger projects can deal with it.
I agree it's an audience problem. I had a Wordpress plugin up and I'd get all sorts of entitled requests, borderline "plz fix my website you broke it". But also had some C libraries for Arm STM32 and only ever got solid pull requests and people eager to help. You see the same thing in IRC / Discord channels of those technologies.
which will be interesting to see if you ask them for payment for fixes, would they pay?
