It’s likely that the first type, of personal power, is included in the other type of power, but what is meant here by “power” is: you get to shape the future and make huge money doing it.
Regarding Ilya’s seemingly contradictory behavior, it appears more likely that he wasn’t really orchestrating the coup.
Instead, he was a pawn, manipulated by other interests to be the public face of the coup. These interests appealed to his ego and desire for more recognition and power within the company. Ilya’s perceived entitlement to a more significant role probably made him an easy target. So, it’s not accurate to say that Ilya orchestrated the coup.
It seems it was orchestrated by other key players on the board, primarily the backers behind the scenes. These backers likely include intelligence and policy security experts fronted by Helen (the AU-UK-China intelligence and security policy wonk axis), and those aligned with military-industrial interests, such as those represented by Tasha (RAND Corporation et al).
This coup had probably been planned for a while, with the goal of removing Sam who created obstacles to their plans. They tried to provoke him into a mistake, and when they believed they saw a moment of weakness, they executed their plan. However, the plan failed spectacularly.
For obvious reasons this would never probably be widely acknowledged, so it may be written up in some more niche blogs on use letters if anyone cares to do the investigative journalism.
As a result, as I previously stated it would be unwise to consider at face value The lies and presented as explanations for the coup, because of the power that is at stake.
Moreover, if you wish to gain a clearer understanding, consider the context into which the obvious players are in bedded.
Their letter claims he was dishonest about something, we will see in the coming months why. I'm still very confused as to why Ilya would seemingly orchestrate such a monumental shift in the company, only to claim his 'deep regret' a few days later. It's pretty odd...
The main theory that fits for me is that he didn't want the mission to become profit-seeking, and probably Sam played down some of the deals he was making, or didn't mention them at all. Once Sam was removed, presumably pressure from the rank-and-file, the hundreds of people he sees everyday who uprooted their lives for a piece of that profit, turned Ilya away from his more pure convictions...
But who knows, this story will be interesting to watch over time.
