That's largely because academia favors central planning and doesn't trust those without a graduate degree to make socially optimal choices. They want to be the planners the masses depend on and Mises tried to show that desire was problematic from a first-principles, liberty-oriented perspective.

What's really laughable is that academia thinks its policy prescriptions play no role in the ongoing economic mismanagement despite all evidence to the contrary and the predictions of the Austrian school. Your need to smear the name of Mises with unrelated controversies is also very telling. Why not let the theories speak for themselves?
