Mocking legacy code is hard. Especially, if it's a third-party library and you have little control over how it's written. It is even more difficult to unit test a type that is instantiated internally. One can argue that it should be refactored to accept dependencies via constructor injection. However, constraints such as time, budget, experience with the offending code, or even access to the source often prevent paying down the technical debt accumulated in these legacy systems.
