It's pretty funny to me. I had a bunch of people ask me to implement features or fix bugs, and I just told them I don't want to spend time doing that. Very few had gotten entitled, and even those went silent when I told them I'm a volunteer.
I think it's still important to let people speak and ask for things, even if you're not going to give it to them. Also I have zero expectation of anyone ever paying me for my open-source contributions.
One nice thing about rude people is that at least they tell you what they want.
