From the "Twitter Files", the platform reporting system has a list of accounts, and those accounts can have different levels of "approval" for moderation. For example, any moderation action taken on Libs of Tik Tok would require approval from a committee [1]. Larger, more popular accounts require more eyes as they're likely to garner more "false" reports.
All of this is to say that there are three likely scenarios:
1. For whatever reason (e.g. staffing, technical problems, lack of training), PG's account didn't get treated with the scrutiny it deserved.
2. A report on PG's account went up the chain, landed in front of a trained moderation team, and they banned him against Musk's wishes (presumably unintentionally).
3. Musk desired his ban.
If it was a random tech CEO, I think Scenario 2 would be most likely. Given the recent technical issues with Twitter, their employee turnover, and Musk's recent actions towards "former allies" that spoke out against him, I think it's actually a toss-up.
