I feel like in the parent comment coup is sort of shorthand for the painful but necessary work of building consensus that it is time for new leadership. Necessary is in the eye of the beholder. These certainly can be petty when they are bald-faced power grabs, but they equally can be noble if the leader is a despot or a criminal. I would also not call Sam Altman's ouster a coup even if the board were manipulated into ousting him, he was removed by exactly the people who are allowed to remove him. Coups are necessarily extrajudicial.
