Such a bad comparison. The correct picture would be 10.000 people from St. Petersburg whose main job it is to drive through my street with a local number plate a million times per day, just to demonstrate to me that there is so much traffic on my road.
The economies of scale for creating sewage in social media are basically unbounded. Tens of thousands of people have a 9 to 5 job which consists of creating sewage content just to steer people towards a certain narrative.
It's not a comparison but rather an analogy. Certainly it's quite a rough one. But it illustrates my key point well enough - that it is realistic to view infrastructure in a more or less neutral manner even when reputations are on the line.
