Just because his family is managing it (IE: employees) doesn't mean they own the assets. The blind trust is most likely with people unrelated to him or the family.
You have a basic misunderstanding of the issue at hand because you didn't bother reading the article. Not only are you ignorant of the facts (what a blind trust is), you then accuse others of insulting your intelligence. On the face value of your comments, the claim that you possess any intelligence appears dubious.
EDIT: HN is an insult to my intelligence.
