I'd say its not the web designers, but rather the poor programmers that made IE, every other browser can do the job from, chrome, to firefox, to opera, to safari... But not IE.
Then there's the continuous security risks, then theres "United States vs Microsoft"... TBH I'm very anti IE, but not anti M$
However I am liking web designers for putting hilarious statements like this one on web pages:
This website does not function properly using any Internet Explorer (IE) browser. Please use the following browsers for best results: Firefox, Safari, Chrome, or Opera. Internet Explorer does not adhere to Industry Standards like other browsers. We can no longer afford to support it.
Statistics also vary widely, from site to site, region to region which I said so earlier as did yourself. But all in all, I'd still say IE is slowly dieing even by various sources scattered all over the web:
