I had organizations leaders before say things that are so black and white like "We should delete all user accounts that haven't logged in 6 months", you say "Are you sure? some people will be upset. Some will post on twitter or reddit and complain etc" they confidently reply "Yes, we will explain that it's not sustainable and they are welcome to create another account". So you go ahead and implement that. 1 second after it goes into effect, you get angry support tickets, a post on twitter, and that "leader" immediately backpedals that "the implementation was not how I expected". Like what did you expect was gonna happen exactly?
But my best guess is they don't want to put a firm line down because they want to be free to shift it around however they'd like.
