It's not like typing in a Faxanadu code. The ransomers are sitting on a mess of confidential information they lifted from Nvidia and they likely have zero clue how it all works. Keeping it to themselves was probably the original plan, but once they got a taste for how tragic engineering is behind the curtain their only chance for recuperating the investment became (1) forcing Nvidia to write the driver update for them; or (2) leak it and hope some open source developer volunteers.
