I thought that this excerpt from the article was interesting. [emphasis mine]
I may have said it before, but there is always some confusion between academic freedom, free speech, and responsible speech. That last quality is an important part of the debate, beyond the collective bargaining agreement (which Tracy violated) or due process concerns.
Academics have rules to follow, especially ones that pertain to handling claims and evidence. Tracy was bound by those rules. Sidestepping that core obligation distracts from his departure from professional standards.
