Research universities have plenty of professors who are there to do research. But they often still have a teaching responsibility. For those professors, teaching students is a mandatory thing they only do so they can keep their job doing what they actually want: research.
Those professors aren't great teachers, and I think we shouldn't blame them for it. Instead we should blame the system that forces them to do something they aren't good at.
This is a problem but it's not really related to the issue of the harsh reaction of college administrations to exposing problems, the examples mentioned in this thread and in the original article are all capital A Administration responses, a group completely separate from the professors. Some professors are involved in admin work but the vast majority of admin work is done by employees who neither teach nor research.
Those professors aren't great teachers, and I think we shouldn't blame them for it. Instead we should blame the system that forces them to do something they aren't good at.
