Just a suggestion: Consider instead framing it as giving a discount to people who use a newer web browser, since "they didn't require the extra work supporting older, buggy web browsers does" (or similar phrasing). It makes the same point, but may be less likely to make potential customers resentful.
Either way, you'll probably want to run this by a bunch of actual customers. People with the sort of personality quirks that draw them to (and make them good at) programming might respond to this very differently than customers/clients at large. Also, note that some people will not be allowed to change web browsers, e.g. for administrative reasons. (Whether or not they're good reasons is beyond your control.)
I don't know if it's a good idea from a business standpoint, but I like it.
Yeah, the way it's framed can be made easier, probably. The "discount perspective" is always easier to swallow.
What I'd like for us to do, as real businesses do, is to turn the discussion into one of costs and stop pretending to our community that IE6 support comes for free.
"You live in Canada and we have to charge you more because it costs us more to send our product to you."
People understand this-- it might not occur to them at first, but I think it might be a good idea to begin showing customers how they increase their own prices. The majority of IE6 users may not even know they cause the trouble they do.
