IMO, the best outcome would be to put Equifax out of business. I have had my identity stolen and they were complicit in enabling the fraud against me. Once you tell them you're NPI has been compromised, they get incredibly passive aggressive against you and refuse to allow you to manage the situation (i.e. they won't let you unlock your credit to apply for a mortgage).
In short, this breach of public "trust" is only the smoking gun that proves how horrible Equifax is. But, they have a long history of being a parasitic organization that will hopefully die soon.
