My money is on a MilTech contract. Same got it approved in secrecy without telling the others; Greg had to know for signature and didn’t tell others. Neither could speak about it, hence the lack of candor, uncharacteristic from fairly straight-shooter Sam. Explains why Eric Schmidt knew to congratulate him immediately and why he’s not ashamed.
Alternatively, Google keeps showing a non-existent tweet of Sam announcing a presidential run in 2024. Maybe the board didn’t like that he didn’t tell them. Also explains why Eric would know more.
