> Libertarianism, it would seem

In some peculiar, perverted sense, given that evaluating claims of disability requires breaching students' medical privacy. You wouldn't normally expect libertarians to so overtly be okay with invasions of personal privacy.

I think they are just commenting on the bias of Reason magazine (it is a well known libertarian magazine).

That’s probably because Reason’s libertarian goal is not to get claims of disability evaluated. The goal is to get the government mandate for disability accommodations eliminated, which eliminates any benefit of making the claims and therefore any reason to evaluate the claims.
