This seems to be the most likely explanation of the events. People say how incredibly smart Adam is. That might be true. Nevertheless being smart doesn't mean he is a good fit for a board seat with such a backstabbing attitude. On the other side Helen, having a fancy title "Director of Strategy at Georgetown’s Center for Security and Emerging Technology" without much substance if you look closely and Tash, both who got their seat as a donor exchange by organisations and people they are closely connected with are clinging to their seats like super glue when almost all employees signed a letter that they don't want to be governed by them anymore. This board is a masterpiece of fragile egos who accidentally got into the governance of a major company without the ability to contribute anything of substance back. Instead they are being remembered for one of the greatest board screw-ups in business history.
