I guees he’s leaving the apology for their current conduct to the future ceo, who can then apologize for that ‘past’ conduct.
Excellent
He has just bought in to clean the place up, and has no connection to the previous misconduct.
His job will take several years, and involve getting rid of thousands of upper level managers and executives. It is difficult to replace that many people at once, so it will be a long process. When he is done, you won’t recognize the place.
