So now the door is unlocked?? Where are the goal posts?

Don't mess with people's stuff if they don't want you to. This seems very simple to me. But I'm aware that you're trying to find some fringy gray area where you think it will be OK to mess with people's stuff even though they don't want you to.

If we're making an analogy to the Weev case then yes the door was unlocked, with the explicit intent that the general public could come through that door and access some of the documents.
