The difference here is this is someone engaging in the public in behavior that contradicts the very field he is a part of.
Vs a personal social media account under anonymity in which case the person doing the "exposing" would have to dox a person to accomplish corroborating the identity of the person posting on social media AND to find that person's place of work to get them fired,(a crime), AND if the postings fall under free speech, there recently have been people who have had this happen to them who have been successful in suing both the company that fired them (violation of free speech) AND the people that doxed them, because they committed a crime.
As I said - things aren't going the way they did early in cancel culture. Many of the people doing the doxing are finding their lives ruined instead when the lawsuits start coming for them - because when some of these companies fire their employees and then get sued successfully, they also want their pound of flesh and go after the doxer too...
