My understanding is, the thing that got him effectively fired, [0] is not the affairs themselves, it was not being candid with his board about the extent of the problem–he admitted to them the affair with Alice Huang, but didn't tell them about his other affairs (including at least one with a direct report) until after the board was made aware of them independently.

A board can put up with a CEO who cheats on his wife. It can't put up with a CEO who hides things from it.

[0] formally speaking he resigned, but it seems likely the board communicated to him "if you don't resign, we'll fire you"
