That's nonsense. Even if Apple was trying to trick him (which they definitely were not), his blog post didn't have to admit any wrongdoing. Nothing he needed to say in there would have been admitting to fraud. It merely would have admitted that his account was linked to one with fraud (which nobody is disputing) and that he's working with Apple to unlink it and restore his account.
I thought his post fulfilled that criteria, which I do agree is reasonable for Apple to request, so I was under the impression that OP was arguing he didn't go far enough.
If his post is not enough, then Apple should consider just sending him a statement including the correct wording for him to use.
He drafted a post and sent it to Apple for approval, but didn't get a response before Apple's PR statement was released and before he reacted by posting that phone call. It's plausible to me that the drafted blog post would have been sufficient, but him posting the phone call probably immediately torpedoed it.
