He might shrug if off as a missed marketing opportunity, but this man has no understanding of how incompatible the the sentence "We don't need no education, we don't need no thought control." is with any of his undertakings, or what it takes to show some respect to values humanity tries to embrace. He exploits those weaknesses.
