Some may see your comment as flippant, but it is very accurate. Didn't MS shut off support for that combination of OS and Browser? If so, their IT department is exposing them to security trouble. If so, their competence is in question.
This isn't being conservative about upgrades. This about an IT department refusing to learn to do anything they weren't doing in 2000.
At worst, it allows independent software vendors a small market for regular repeat business. At best, people just keep using XP the same way they've been doing for years.
