They are not Willing To Change. This sounds like an AntiPattern. Possibly related to If It Is Working Dont Change, but without the conditional. ;-)
They could be afraid of change in general, or it could be that they don't trust you because you're not One of Them — you're outside their Community of Trust — and thus anything you do is Not Invented Here and a scary mystery.

Perhaps they are gambling on being able to use you as a ScapeGoat, but to do so requires that you not actually fix the problem, so they make sure you don't.

Reminiscent of heavy wizardry... but with deeper magic.
