They do say "not entirely", implying that it can be used for some manipulation. Specifically, manipulation in the form of "cognitive bias in people's behaviors". I imagine I couldn't manipulate someone into buying a product they have zero interest in by changing their breathing, but I could subtly influence/bias how they feel when first observing a product. Is it manipulation? No, not entirely. That being said, I would still be cautious about any sort of abuse.
