While I tend to agree (and have actively chosen to not publicly post that specific info myself), I'd argue that given the vast number of people who received that communication from him hardly qualifies it as 'private', and nondisclosure was not specified as a prerequisite for receiving it.
"I'm telling you a secret, but don't tell anybody else" rarely works.
FWIW, I did remain on CT as a active contributor after the mass exodus here to PCF (while simultaneously protesting CT's management's treatment of the paying members), and was promptly publicly shit on by first his mommy, and then by him, wrongly backing her up. I've since let karma deal with it, and it's done a fine job as far as I'm concerned. Fuck that guy.
