But still, making your app/service compatible with IE6 is a hassle for you and preventing you from doing a better job in other areas which harms your profits.

Perhaps we can take the hit for you. We could cause your customers to stop using IE[6-8] by specifically not fixing the sites to be backwards compatible. Your users will note that although your site still works in IE6, every other site won't. Then if we can drive down the 10% IE6 users of your site to 1%, then will you stop spending time making things compatible for it?

Sure, it'd be great if everyone used a modern browser. I don't think it's ever a good idea to intentionally punish users, though. I'm pretty sure anyone using IE6 (or 7 or 8) is very aware they are on a crap browser. Tons of sites have told them or just appeared broken. They likely aren't in a position to be able to do anything about it.
