I’m finding out if its allowed, that a ChatGPT Plus subscriber can share their account with, say, their immediate family members under the same roof, like Netflix does.
The terms of service say:
You may not make your access credentials or account available to others outside your organization
which implies you MAY share accounts if they are WITHIN your organization. But what is an organization? 
Maybe this is a question we should not make them answer directly 
like, just do it and don’t make them have an official position. Well, I don’t want to try it and get banned.
