Of course he is. He HAS to. Unfortunately he's not doing it because he's a good person, but if he wants Twitter to have ANY viability as a company, he absolutely can NOT allow the kind of nonsense that Kanye West is currently spewing. Advertisers will run. Apple has warned that they will take his app off their store if he doesn't dance.
I saw this compliance coming down 5th Avenue. As soon as there were reports that he was interested in buying Twitter and Trumper got all excited, I knew they should not be so excited.
When you run a company that is advertising-driven, you absolutely can NOT do whatever the hell you'd like to do.
So, Elon Musk will dance. Dance Elon, dance!
