It's not asshole-ish at all, it was just direct and made the point much clearer with the proper amount of urgency. This bug crashes sites consistently and is easily exploited. That's serious enough to warrant an immediate fix and release with an apology for the design. That's what I've done on my projects, and that's what I expect.
Now, the question is why do you demand humility from me, but not from them?
Seriously? A bug report that identifies a DOS condition gets flagged as "won't fix" -- and Zed's followup explains, with details, why it should be fixed, and what the fix should be.
I tried, and I couldn't find anything asshole-ish about the bug report. It looks like good work to me.
