I think a lot of this discussion misses a very simple point. When someone invites me to come to an event or something else that sounds like fun, but they say "hey, I want to include you, but you gotta keep this on the D/L, I don't want this getting out," then I keep my mouth shut as long as it isn't hurting anyone.
Nobody has some weird right to see what is going on at practice, and if any of you have ever shared something with me in confidence you know that it has stayed in confidence. It is just part of being courteous to the person who asks you not to share something. It isn't a conspiracy or something weird, it is just good people keeping their word when they say they won't spill the beans.
