Who on earth has to justify a javascript framework to their boss? There's so much competition and, unlike in the C++ or Java world, there's no agreement about what's best. Even Microsoft and Google haven't hammered down "the solution". Many projects use 2-3 frameworks.
I've worked at (and am now working at) some pretty big companies, and I've never heard of such a practice moving over to web development. There is usually just a license audit and that's it. And if you're a consultant justifying your use of jquery to your client, you are doing it wrong. They don't care what you use, they care about what licenses you use and how it works when you're done.
I think the complaint itself is "puerile" and pretty darn shallow. The illustration may have been ugly and as one of the original people to have an official job title of "ruby on rails rock star" I'm kind of tired of the metaphor. But I'm not about to throw a giant multi-venue tantrum and poop on the jquery guy's fun.
