No. He's just interested in it and really doesn't care at this point what folks might think. Personally, I find his honesty refreshing. It's something I'd look into as well if I had his resources and contacts. It's possible that those who want to keep such subjects in the dark are psyopping him to attempt to discredit him. He's not afraid to say what he thinks, and has a hell of a platform to do so. Wish we had more like him.
