Is there a history of that here? Were there earlier clear statements of expectations (like CONTRIBUTING.md) that expressed the same expectations, but in a straightforward way, that people just willfully disregarded?
I don't mean to "ding" anybody, I mostly just felt bad that things had gotten to the point where the author was so frustrated. I completely agree that project owners have the right to set whatever terms they want, and should not suffer grief for standing by those terms.

I have been maintaining not-super-successful open source projects, and I've had to deal with entitled jerks. Every. Single. Time. I am totally convinced that any successful open source project sees a lot more of that.

IMO it's not needed. I don't have to clearly state expectations: I open source my code, you're entitled to exactly what the licence says. The CONTRIBUTING.md is more some kind of documentation, trying to avoid having to repeat the same thing for each contribution. But I don't think anyone would write "we commit to providing free support and free work someone asks for it" in there :-).
I don't remember the exact situation, but I think this relates to this:
Clojure core was sent a set of patches that were supposed to improve performance of immutable data structures but were provided without much consideration of the bigger picture or over optimized for a specific use case.
There's a Reddit thread which provides a bit more detail so excuse me if I got some of it wrong: https://www.reddit.com/r/Clojure/comments/a01hu2/the_current...
