Why? Breaches like Equifax happen when companies treat data, especially personal data, as an asset rather than a liability. Treat their database as the toxic asset that it is, and delete it as part of the bankruptcy.

Then what do you sell? You can’t sell the company and distribute the money to the affected people if you make the company worthless first.

They've already shown themselves to be terrible stewards of that data. If it was sold due to their bankruptcy then whoever buys it is going to be much more careful about losing any of it.
