I don't believe the pretext for the cancellation
Don't misunderstand. A star tweeting offensive inflammatory things amounts to reasonable grounds for a network to take punitive action.
But I suspect that in this highly partisan, divided, irreconcilable social fabric of ours, they were just looking for a reason to dump her show. She came out as a Trump supporter and her show has really resonated with middle America and many of the people who went to the polls in 2016 and took the country "off script".
I suspect as much because of what happened to Tim Allen's show Last Man Standing. ABC also canceled that show when it was doing very well in the ratings. Tim Allen is a Republican. More specifically, an OPEN republican in Hollywood and his show was popular among middle America republicans and conservatives. The strong numbers were all there and yet they chose to cancel the show.
I believe it is primarily ideological. There is a cultural war of sorts out there and the ABC people don't want to help their ideological enemies.
Now, do I think it is their right to cancel these shows? Sure. It's their network. And, Roseanne, as opposed to Tim Allen, actually gave them a good excuse for the decision. I don't like their reason (their actual reason) for doing this, but it's their choice to make.
Mainly, I feel bad for the many many people - craftspeople, technicians, crew members, office personnel; and supporting actors and bit players - who are now going to have to look for new work.
For the record (since I'm sure you all are just dying to know): I personally have not viewed either of these shows, so this is not coming from a die hard viewer who is upset over the loss of a favorite program.
