I think that "manipulate people for financial and political gain" is an outcome of what social media companies actually do - I was under the belief that in a general sense, they want to maximise the time people spend on their apps so that they can sell this attention to advertisers, independent of whether or not a given ad buyer wants to manipulate people.

This is where they manipulate in my mind. They maximize that time by exploiting human psychology, manipulating people into scrolling their feeds endlessly eh?
