> …and when someone asks for your permission (probably because you’re in the person’s management chain), one response could be: “you don’t need my permission, if you think it is a good idea after getting input, go for it. If it turns out to be a bad idea, share your learnings so we don’t repeat the same mistake.”

That's all fine and dandy, but once you decide to weasel out of giving your input once asked then you lose your right to feign ignorance and surprise about hypothetical "mistakes" because you too failed to spot them, let alone address them. You had your chance to avoid a mistake when the mistake could be avoided. That was why your input was requested. If the mistake was still made it was because either you were not able or were not willing to spot them, so you have no right to point fingers at anyone but yourself.

If there's anything ruining teams, it's the sociopaths that try to get ahead by setting up their team members for failure and backstabbing them while feigning ignorance.
