The pro blaming evil billionaires case is basically that web1 (esp internet forums) is widely considered to be a much more unbridled source of good, and it's specifically social media that's considered the dangerous thing. Both are "internet". The differences between the two are (i) stronger capitalist optimization pressure on social media, (ii) audience of social media is less selective. So you can tell an anti-capitalist story ("algorithms maximize outrage because it gets attention because that's what investors want"), or an elitist story ("culture only works when right-curve discourse sets the top-level narratives; the internet forum as a medium selects for right-curve, but social-media selects for mid-curve"), or possibly some mix of both
