I don't know exactly how many of the issues are real. Since of the ones I listed only 3 of 5 were real even by your count, I'd be surprised if none of the others were at all questionable. But even if we accept that they're all real, hair-on-fire problems with vanilla JavaScript, I still think you're going too far. At the very least, jQuery is not the only library out there that handles compatibility issues. Lots of people who use other libraries do not "need jQuery."
Basically, I think you have made a much broader claim than you have been able to support so far. I'm absolutely not trying to knock the hard work of the jQuery team or suggest that jQuery is useless. If you had just said, "jQuery is still really useful. Here's a few things it does for you that you'd never think of," I'd have said, "Great post — thanks for reminding everyone." Instead, you took a very hard line that came off as pretty combative, but your supporting examples were really shaky. So I disagreed.
