This is a "too big to fail" event. Getting rid of or changing Equifax would disrupt too many other businesses, therefore any wrongdoing of theirs will be waived away and the costs pushed onto consumers.

Equifax were already in the process of having the law rewritten in their favour by the Republican party, at least that might be derailed or delayed for a few years. https://www.americanbanker.com/news/equifax-breach-may-kill-...
