They really don't have a choice. Every aspect of your "credit score" is governed by law.
One particularly egregious example: banks and credit agencies are FORCED to ignore bankruptcy after 10 years when decided whether to grant a loan to someone. Even if a wealthy person default on a 100M loan, even if he has multiple bankruptcies in his past, banks must ignore them if they are >10 years old.
Credit agencies are private companies, but they play by the government's rules.
