The part that I was especially interested in was the fact that by controlling the opaque algorithms that determine the output of the variable dopamine hits--likes, views, featured content, trending content etc.--they are able (no doubt with only a broad precision), to influence emotion; influence emotion over an extended period and you're influencing mood; mood is massively linked to decision-making, which is where the other pincer you may be driven towards comes in: increase dopamine, elevate mood and risk-taking increases. At this point offer gambling or pseudo-gambling propositions: lootboxes, credit card applications, bookies' advertisements. Conversely, shadowbans, technical failures, dwindling likes, initial downvotes, videos in restricted state, reduced advertising revenues and repeated failures to trend are depressing for those who virtually live online and depend on social media for income. In this scenario, the other pincer appears in the form of councilling, pharmaceuticals, pampering products, 'educational' opportunities and dating sites: all to drag you out of the rut they have dug for you--at a cost.
