I believe Equifax is currently facing 240 state and class-action suits. Still doesn’t seem the appropriate way to handle an entire nation being affected by their failure.
Unless those actions pool resources and forces, Equifax stands a good chance of defeating most of them in detail. String most along, cherry-pick the most likely to prevail against (with a combination of lobbying, legislation, politicking, marketing, and legal maneuvers), win or stalemate those, then work their way down the list with those precedents in their negotiating back pocket.
