I'm arguing nothing, and am trying to better understand why people are continually claiming it was their "greed" that caused this failure, and not their incompetence.

They didn't seemingly pursue a strategy that would have resulted in their pay increasing meaningfully, in fact it seems like they pursued a strategy they believed was safe and cautious. It wasn't, but they did seem to think so.

But I don't have all of the facts and this is not my wheelhouse, so I'm asking questions for clarity. "I don't know" is a reasonable answer, but not one I find around here much.
