I agree that the response is a bit snarky and escalates the situation. However, unpaid open-source project maintainers aren't obligated to be scrupulously polite at all times no matter what. If you want professional corporate interactions, then pay professional corporate prices.
I'm also sympathetic to not wanting to commit to a specific release schedule for an open-source free time project, with implied consequences if it isn't met.

It would have cost mhils nothing to be polite and the idea that "if you want polite then pay for it" justifies abusive behavior.
I've personally seen far too many co-workers state that they're paid for their technical skill rather than to be polite, or even that they're not paid _enough_ to be polite.
