sure, that's "what people want" inasmuch as if you put every button through a statistical microscope, that's what the statistics will tell you, but if you give a rat cocaine-dispensing button and measure how many times it hits the "more cocaine" button you'll also come away with the conclusion "rats want cocaine", a thing they never encounter in nature and would never have encountered without you putting it in front of them, and you'll pat yourself on the back and say "now I understand rats: they are all vicious cocaine fiends", but you haven't really learned about rats' true nature, you'll have only conned yourself into a false narrative that confirms that your own actions are only "giving the rat what it wanted", and after it dies of an overdose, you declare yourself innocent. Anyway that's a/b testing and the tech industry.
