I don't think this got too much to do with IE. Any other browser with such a big marked share would get the same hit. No connects computer is secure these days, independent of the browser!

The only secure computer is a disconnected one, believe me kids, I've been in this branch for a long time.

I believe this got much to the with EU attitude, and tired IT-advisors on government pay role, advising some tired politicians which most of them needs help from the grandchildren to turn on their computers, against M$ monopoly. I hope those tired people consider the effect on the business side too.
