Right to be forgotten is fine for people who aren't celebrities. If you want to be forgotten then don't have a CEO job at a huge company.
Also it generally applies to situations where people are associated with a crime and either there wasn't enough evidence or they already served their time. Neither of those is true here. He has faced nothing except people being mad at him for something he definitely did.
It would be so easy for him to say he changed. Why should I pretend it never happened if he won't do that little thing?
