My first thought was: gray text is explaining what the toggle does. But then I read the text and it made no sense: if I _restrict_ sharing, it will allow people to save and forward?
Okay. Second idea. It might be explaining current state of the toggle. That would be wrong (don’t to this! always explain what toggle does when enabled), but at least I can understand the thinking.
So I enabled it and the grey text didn’t change. Now I’m out of ideas.
