Thank you for the reference - I agree, that's the most likely interpretation of the email. I wonder why this wasn't called out more strongly when the hedge fund was mentioned in the press release.
You misunderstand. Your email _address_ (and mine) have already been leaked, shortly before Christmas 2011. What WikiLeaks is now publishing is a list of actual internal emails, as in, the content of their internal, private communication. Unless you were a source for them, or a buyer of their more confidential information, you won't be directly affected by this leak.
De dure, not de facto. Show me a report of someone getting arrested for it. Hence my accurate description of his ridiculous scenario appealing to a slippery-slope style train of thought. Case closed.
It is not an analogy. What is the analogue? The slope is descending from now (you cannot get arrested for singing happy birthday) to then (you can). Slippery.
