This is an issue that allegedly involves Musk's family. He's tweeted about it directly multiple times stretching back to his initial offer of cash for @elonjet to go away, and has directly discussed this policy change in his own tweets over the past 24 hours, including tweeting about this round of bans.
Are you actually saying "it's hard to tell whether Musk is directly involved" in this specific issue, or...?
Whether those banned were actually in violation of those rules I don't know. I would have said remains to be seen, but I fear such details will be lost in the news churn.
