There is one element of Gary's ouster that was never quite clear to me: when he was removed as CEO was there any option floated for him to remain with TSR? The received wisdom is that he was "kicked out of his own company", but the meeting minutes only address the loss of his senior management roles.
"Creative Director" would have been a step down, but he was better suited for it than CEO or President. Was there no option proffer, or did Gary declare "Settra rules!" and refuse any option that did not leave him at the top?
Also, re the "ambush" nature of the meeting. It never would have worked if any of the people involved decided to support Gary. If there was one person among the board loyal to Gary or thought he could save TSR, the plan would have collapsed. Evan the Blumes chose not to whisper in his ear in the hopes of starting a bidding war for their shares.
It was the scenario when the leader with his minions at his back declares that he will any foe, only to realize that everyone backing him starts easing out of the line of fire. If it was a palace coup, it was done with the full support of the country's ministers.
