I don't think anyone implied that there was anything wrong with sharing the article. It certainly did contain some interesting information.
But...it did come across as arrogant and condescending. It was not nearly as professionally written as his arrogance and self-importance would imply. In fact, it was a very poorly written bit of work and based simply on that context, it does not surprise me that he's not more published in the scientific journals.
This is NOT to say that he doesn't know what he's talking about. He's obviously very well educated and passionate about his work and his knowledge. He's just not particularly adept at passing that knowledge along to his audience, unfortunately.
