Almost always when I see a statement of the form "people in group X are doing two contradictory things", it's very likely that it's different people in group X that said those things. You're creating strawmen. In this case, even if the same person criticized Brian Armstrong then later congratulated him, I don't see the issue. Humans sometimes achieve things, sometimes do controversial things, it's as mundane as it gets.
