Why You Should Stop Supporting IE10, IE9 and IE8

Should and can are vastly different things. It's going to be impossible for me to make the business case to my CEO that we no longer support IE10 if 25% of our business travels through there.

Some people are locked in - their offices haven't upgraded and you run a B2B site (i.e. working with a government or slow-to-adopt business), you simply don't have the luxury of throwing away business just because they're not supported.

I'm all for everyone upgrading, but reality doesn't always match expectations.
