Disclosing private communication is wrong conduct.
That's a generalization that is not always true. Sometimes disclosing private communication is unethical and/or illegal and sometimes it's not. In fact, sometimes the only right conduct is to disclose private communications!
Do things responsibly and ethically, ask the sender first.
It is a responsible act to ask a sender before sharing their communications, but it is not necessarily an irresponsible act to share a sender's communication without asking them. Sometimes the right thing is not to inform a sender you are going to share their communications.
What is your point of view Marvin?
That you've made much ado about nothing in this discussion. The original poster has done nothing unethical, immoral or illegal in this instance insofar as I can see or has been shown. My point of view is as I've said earlier, that you're showing the south end of a north bound horse. That's what I'm seeing because that's what you've shown. Just above you go on by quoting legalese. If you think anyone here has broken a law my recommendation is that you call local law enforcement and report the crime. My view is that you're making a mole hill out of flatland by forcing details into a very narrow and self-serving clump you apparently think of as "fact".
