Those work together. But I find the most insidious aspect of these platforms is how it allows companies to exploit our vulnerability to unhealthy behavior. Even if you grant that Instagram's content isn't toxic (which it is, but just hypothetically), the ads are terrible. I, for example, don't drink. I was never an alcoholic per se, but I had an unhealthy relationship with alcohol, and in many ways I miss it. Instagram shows me ads all the time trying to convince me how fun it is to drink, and why so-and-so drink is delicious and amazing. Now extend this to shopping additions, misinformation campaigns, et cetera.
