My curiosity stems from whether the board was involved in signing the contract for Microsoft's investment in the for-profit entity, and where the state might set the bar for fraud or similar crimes.

Did the manner in which they conducted this business rise the level of being criminally negligent in their fiduciary duty?
I feel like there are a lot of exciting possibilities for criminality here that have little to do with the vote itself.
