And your point is? Pointing the blame at a different source doesn't mean the problem isn't present. If a client needs IE support, what do you do? Write the code three times? Detect IE and redirect the user to chrome-frame, then cry when you don't get paid?

I don't care who caused the problem. Just that it wasn't me, I can't fix it, and I have a deadline to meet and constraints to follow. jQuery is a lifesaver.

It's a developer's problem.
