Indeed, this is most puzzling and it is now a 33% chance that he's the one that started all this. If it turns out that is true the chances of a successful suit go up considerably.
That might cause the board to split up further, there is already one defector from the 'gang of four'. If D'Angelo started it the other two might say they were pressured by him and come out publicly against him (like Ilya Sustkever did).
I'm starting to wonder if it was a gang of four or if it was a gang of three and they used one of the cofounders (Ilya) to turn on his cofounders to get control of the company.
Likely the second or it was a gang of one who used the inexperience of the other board members to get them to act against their own long term interests. That does not absolve them, they are still board members and they should own their decisions.
I know it’s nuts, but is there any chance this was orchestrated to some degree? If someone wanted to throw off the non profit structure, they couldn’t have done a better job than this. I mean, it really works out well for Microsoft.
