I think that $400 million could be a lot more complicated to handle than most family accounts, especially if the family was aggressively trying to minimize their tax liability, which they were. And the finances really started to get complicated because the husband started to hide the money when Pusgrove found out about the affair. Also, the legality of the business is questionable. It looks like the money was made from adware. So I would not expect Pusgrove would want to take much credit for the management of the company.
Surprised actually. If she really did run the company "day to day", seems like she would be in a position to give him the boot (grab the accounts) vs. what actually happened.
