Not just open-source maintainers but also moderators. A bad thing about moderators is that nowadays they tend to be immature teens, it's one of the reasons Reddit content quality has been going down in the past few years. It also creates some moral questions, as companies with giant revenues are outsourcing their internet janitor duties to naive unpaid child labourers
I think (mainstream) Reddit content is something completely different; more like big clumps of PR firms employed by corporations and lobbying groups bitbotting around with nation states, all fighting and agreeing with each other and trying to build false consensus. Source IP analysis there is probably pretty interesting.
Have you ever worked with a PR firm or talked to folks that work at one. Have you ever worked at a large company, or talked to people who manage social media at one? They are very far from this level of coordination. Most can't even manage to deploy a properly measured ad campaign, much less some kind of op sec driven Reddit content campaign.
