> Reading between the lines, what probably happened is that Jensen didn't come totally clean with the board on Nov 8 and tell them about the 2nd K Powell affair. Instead, the board got totally blindsided and lost trust in him. (Is there another 3rd secret affair he's hiding from us?!?) It was impossible to keep Jensen under those circumstances.

Yeah, this seems likely. It's also quite possible that he not only "didn't come totally clean" but outright lied to the board i.e. "this was a one-time thing"
