If any statement can be demonstrated to be untrue I will gladly correct it . Indeed I have a professional obligation to do so, just as I have a professional obligation to speak out as I have done about actions which I believe are unethical, improper or unlawful.
Resorting to legal threats or making complaints is over the top and unnecessary. If anyone has evidence that any of the statements I have made is incorrect, the normal (and simplest) remedy is to simply produce that evidence. (Indeed, making threats without having any such evidence would be an abuse of process in my view, and unlikely to succeed, since I have taken great care that all my statements of fact are evidence-based.)
