Fanservice can be good, but it’s up to the author if they want to go through with it, even if that also means it’s up to the fans if they want to indulge. In the same line of thinking, we have a fine line between “canon” and “headcanon”.
The rule also applies to associations. Suppose people in it begin to disassociate from other members. They shouldn’t consider it “wrongful” on the part of the leader and do the whole “oh noes I was removed” routine. It’s an extension of the people who formed it, and imagine (excluding hostility) you being the one in charge and having your claims to your niche crushed. To be an outsider is simply to lack the status of an insider.
