1. Ilya was on the board and deeply involved with the original decision to fire Sam - he in fact delivered the news to Sam.
2. Ilya has since had a change of heart, saying he regrets his participation in Sam's firing, and even signing the employee letter demanding the board resign.
3. But obviously since Ilya went along in the first place, even if he wasn't the "ringleader" as many originally assumed, he must have had discussions/evidence presented to him that convinced him that Sam needed to go. While he obviously underestimated the chaos this would cause, he must have known this was a huge decision and not one he would have taken lightly.
So my point is, why doesn't Ilya just spill the beans if he is now on "Team bring back Sam". Why doesn't Ilya just write a letter to Shear saying this is why he decided to fire Sam in the first place?
God I'm having a hard time imagining how the Netflix version of this will be better than the real thing.
