You don't have to take everything Musk says seriously. He speaks like people would speak in 2000.
On Twitter everyone has his own page. There is no reason why anyone should feel associated with political content from others. I would not feel associated with Ahmadinejad (who was uncensored all the time) any more than with a purported far right poster.
The whole thing is a storm in a teacup by people who want government censorship and cannot tolerate different speech on pages other than their own.
How about leaving all .com domains because there are a couple of right wing ones, too?
