Sure, I get that it's a big company and that not everything it does involves selling people dangerous drugs that ruined their lives [1], while simultaneously consulting for the government regulators that regulated those drug companies [2], or aiding government corruption [3], or assisting dictators with their assassinations of pesky journalists [4]. But it's all the same company. I wouldn't want to work for big tech either, but to imply that McKinsey can be better than them in _any way_ is completely laughable.
