As someone who done open source for a long time now, I think the newer generation of maintainers is missing one of the most powerful tools we have available as maintainers.

Ignoring others. You don't like the question? Ignore them. You don't feel you have the time to support them right now? Ignore them. It feels like they are entitled? Ignore them.

I don't think people asking others to work for free is anything new. The recent outrage about others asking you to work for free is relatively new though.

You're publishing open source code because you feel like it. This also means you can run the project however you want. Tell people to fuck off if you don't like them. Or don't tell them anything if you don't feel like it.

You'll feel much better as a maintainer once you act exactly like how you feel like it, no more and no less. Don't pay too much attention to what others say. Time is much too limited to be outraged at everything. Calm down, and ignore people you don't like.
