I did not say it can only be used for personal relationships. I said it only _works_ in such relationships. Because that is a fact, once we narrow it down to its original definition.
Of course you are free to use whatever words for whatever you want. But it means someone who wants to be able to clearly communicate loses their ability to do so. I am asking people to reconsider, and be precise. If you call that "gate-keeping", we can start a whole new conversation about what "gate-keeping" actually _means_. Because if we do not agree on definitions of words, we simply can not communicate with each other.
