This is probably going to be back-pedalled faster than Tony Abbott running from gays on a boat.
I like your style. The whole thing stinks like lawyers fishing for business. Had they just left it alone, without the lawyering and heavy handed threats, it would have faded away and been forgotten in short order. The thread would have been buried away amongst the other bazillion now inactive threads. Doing this ensures that they generate huge amounts of negative, national publicity and probably some kind of backlash, and be ever associated with "Oh that WCS mob, you know, the ones that try and sue people to keep them silent".
You scratch my tape, and I'll scratch yours.
