So basically, he objects to the discipline of mathematics itself. The field is inherently social, because without a sharing of ideas, and in some cases without direct collaboration, progress isn't possible. That said, I have no problem with his choice, but it would be nice if he would at least release a good explanation of what he feels is wrong with "the establishment." I suspect he would be able to discover more mathematical truth if he would at least be somewhat in touch with the mathematics community.
The "sharing" that goes on in most scientific fields is not of the friendly kind. The race for publications (-> money, fame) is the root cause. Ethical values are a facade.
