In an alliance where I was, we had three CiC (mixed from three alliances), one of them did not act as such and one of the other two was tremendously aggressive and warmongering, which prevented the advance of the alliance, dedicated only to attacking other alliances.
At one point, a meeting was held between the members of the alliance excluding these two CiC (the one who did nothing and the one who just wanted to throw us all into his eternal fight).
After a long conversation and an intense vote, it was agreed to leave a single CiC in charge of the alliance, removing the other two CiC from their rank.
In other words, about 40 people supported the change of command of the alliance and another eight were undecided or against it.
They were offered (all) the possibility to continue with us or to leave and create another alliance that would be dedicated to what they liked so much and most of us did not want.
The CiC that did not exercise remained in the alliance the same, doing what seemed good to him and the other left with some of his acolytes. Soon they disappeared as an alliance.
And this is only History.
