&gt;  I would very much not like to be manipulated no matter if the cause is &quot;good&quot; or not.<p>The problem is the definition of &quot;manipulated&quot; is not black and white. Consider the relatively recent change in StubHub&#x27;s fee model. Consumers will always tell you they hate having a service fee tacked on at the last minute when checking out. So, for a while, StubHub tried all-inclusive pricing on their search results, and consumers said they liked the change. However, it ended up tanking their conversion rates. When they A&#x2F;B tested putting the fee on last, they immediately saw an increase in shoppers willing to buy.<p>Is this manipulation? The fee was still clearly stated on checkout, but I imagine the subconscious thought process of shoppers was &quot;well, crap, I&#x27;ve already made it this far, I just want these tickets now.&quot;<p>I agree some of the outright &quot;tricking&quot; examples from the article are over the line, but most forms of marketing are manipulation in some respect. When does &quot;persuasion&quot; become &quot;manipulation&quot;?
