It surely is not hypocrisy.
If we take your assumed progressive/traditional divide, we have liberals supporting liberals and criticizing traditionalists. There is no hypocrisy there.
The more real situation, where a variety of viewpoints exist, Curran was a scholar whose academic freedom was threatened while Weinandy is a Church professional who is supposed to support loyalty to bishops and Pope. W failed badly in his job with the US bishops while Curran has a long active career as a scholar. W deserves to lose his job, but not his academic appointments, if he still has any.
There is irony in Weinandy’s situation, if not hypocrisy, since he once criticized those who opposed the Pope, and now has lost his position for criticizng the Pope.
