"If they saw ie6 as a problem and were willing to put in any effort whatsoever to fix it"

They are now atoning for past sins. I don't think they understood what a pickle they were getting themselves into a few years ago by saying, "Our in-house apps target IE6, our corporate standard browser". Also, they have vendor contracts which do not state, "We guarantee isolated product upgrades to support Microsoft's current browser" or similar. This isn't to say that they shouldn't have been more forward looking -- it's just the reality of the situation.
