There is righteous indignation out there on ABC cancelling the Kimmel show. A lot of folks saying it is "UN-predicted!".
My recollection is that Rosanne Barr had a show called "The Conners" that was cancelled at the direction of the administration (Obama? Biden?) , I am not sure which, because Ms. Barr had made a social media post they did not like.
I think this went to the SCOTUS who upheld the cancellation.
So cancelling Kimmel is an allowable corporate action. We can debate whether or not Colbert was "cancelled" or just not renewed . . .
