Note the author here is presumably not so concerned about the decline of the institutions given his flag-waving for censorship in previous years, eg:

"Banning Trump from Twitter and Facebook isn’t nearly enough"

Even if you dislike Trump, the campaign to suppress conservative voices of the 2010s (now largely reversed) that he argues for there was a significant contribution to the decline in authority and respect that academia has had in the eyes of the general populace.

To be clear, the same must also apply to any suppression of liberal voices - its unacceptable in a culture that claims free speech.

But I am sceptical that this particular writer has a moral high ground from which to opine.
