>Uh.... yeah, it's a company, not a charity.

While this is true sites like Stackoverflow very much only function because they create the illusion that it is in fact a "community". The moment they make explicit that there is monetary value in the knowledge people post on the site it becomes obvious that the users are, using Varoufakis term, technoserfs.

You're very much never supposed to notice that Reddit, SO, and so on continously extract value out of work you produce, at worst you're maybe supposed to notice an ad or two. Because if you do notice that you might actually start asking why you aren't getting paid. Which is btw funnily enough exactly what news organizations and SO have realized vis-a-vis openAI.
