The statement "The authors are badly paid researchers" is completely incorrect. I chose one out of the 7 people mentioned in the article at random. Check the other 6 and I'm certain you'll find at least 3 are wealthy.

I don't know what to tell you. I am a researcher (previously at Yale, now at MIT), and I very rarely hear other researchers complain about cancel culture. Largely, I hear horror stories of abuses of power with no repercussions or accountability. It's only, again, a small cadre of professors complaining about this.

It's only a small number of people who are rich AND have courage that are speaking out yes. The rest are frightened and yield to the mob. This is the insidious problem with the whole situation.
