It is repellant that others can laud his scientific mind but then ascribe to him the gullibility of a small child in any other matter, particularly in this case. He said clearly that, had he attended, he would have used the opportunity to criticise Israeli policies with respect to the ongoing occupation. Clearly, he held that view before he decided not to attend. Disagreement with his decision is fine, but don't insult the man or posit that he was bullied when he wasn't. Respect his right to make his decision even if it is not the one you wanted, and similarly, respect the rights of individuals everywhere to protest Israeli policies in any of the non-violent ways they see fit - whether it be political activism in an NGO, BDS or blogging or anything else. To do anything else is rank hypocrisy.
