Right, but the picture those statements painted collectively was not flattering. And that was certainly intended by the authors. Thus, critical, but not at all "incendiary."
Update: To clarify, my personal stance is that the critical tone was both intended by the authors and, in my opinion, appropriate given how much power Mr. Altman holds. If he has a history of behaving inconsistently, that deserves daylight.
Are you arguing that because the authors knew the pattern they were documenting was unflattering, the piece is somehow compromised? That they clearly had an agenda? That's called reporting. They called a hundred-plus named sources and the picture those sources independently painted was damning. Altman has a history of telling repeated, easily-checked lies, followed by fresh lies when caught in the first ones.
Are you suggesting that they should have "both sides"-ed by reporting company PR and Sam-friendly sources and giving them equal weight? Sometimes the facts point in one direction.
