This was the most recent incident, but only the most recent.  Since the Twitterati tend to encourage each other in juvenile behavior, it might be worth sharing some representative  correspondence I've gotten.

From a senior philosopher at a top 25 PhD program:  "Great work on calling out the idiots in our profession (and elsewhere) in the TERF wars.  Stunning to observe, and mind-boggling in much the same way as watching our kakistocracy operate!"

From another senior philosopher at another top 25 PhD program:  "The current climate makes me nostalgic for [Georgetown's] Mark Lance's nastiness and virtue signaling; can one responsibly do otherwise than to strongly warn potential PhD students against considering Georgetown?"  Though as this philosopher added, it's a "shame" since "there are serious people there."

From a philosopher at a top 10 UK program:   "I hope post-graduates in other disciplines act like idiots on  twitter too, otherwise it will be another distinction philosophy does not need."

And, finally, a dean (not a philosopher) at a liberal arts college:  "This behavior is very surprising.  I would have reservations about letting our department hire someone who acts this way on social media platforms."
