As someone who once held the title of assistant professor, I have little patience for people who recognize that the system is in many ways repulsive, and yet refuse to even consider to stop playing the game because it's all that they know.
The amount of bullshit being produced and regurgitated in academia needs to be called out. Your definition of "unprofessional" is just "this makes us look bad"
Academics who defend a broken system are a major factor in why that system continues to decline.
I'm glad the OP wrote this article and find it expectedly discouraging that someone creeps out from the woodwork to try to shush it.
