Absolutely not. He has been posting here for about a year. If he was concerned as you stated, then he would have stopped making comments long ago.
I personally think it is just as he stated. He is just done with his posts suffering from deletions but those that attack him do not always suffer the same consequence. I think he truly believes that the science doesn't work. But I also think he let his own biases cloud his sight lens. I think he will be man enough to come back and admit when he is wrong. That time will eventually get here. Until then, patients continue to be treated according to Phase III protocol, the study is on-going and 248-patient events have not been announced.
