Those are three anecdotes, and at least two of them are not as stark as described. The data scientist's timing was bad and his prior relationship with several stakeholders was already on the rocks. There are rumors that the worker who had no idea what the connotations of the ok symbol are has been re-hired. This is hardly anything compared to the armies of celebrities who signed the Harper's letter and are mostly complaining that they can no longer express their opinions without being criticized.

The difficulty here is that several things are happening at once. There is a problem with groupthink at some institutions, but there are also people who are trying to suppress legitimate criticism.
