Usually, when a company (e.g., a shampoo or cosmetics company) says they don't test their products on animals, they don't conduct cruel tests at all. But here, the company, while technically not experimenting on animals, instead does the much worse thing of experimenting cruelly on humans --- as evidenced by the man running in a hamster wheel in a cage.
