Some companies will never update, just as some are still using mainframe systems. They will have to live with the repercussions of that decision. The decision being to become reliant on cowboy coder products that were designed only to work in IE6.
I have been a web dev long enough to know that coding for IE6 only is an intentional decision made to increase support costs and is highly unethical. Any company fool enough to employ developers bad enough to do that deserves what they get.
Or they can suck it up and deal with some change for once.
