For the people who make their living owning property, having people do most of the labour for free is the best deal possible, and they still couldn't make a profit, or a useful mobile app, or an actually engaging website.
Somehow, after almost 20 years, Reddit still doesn't have an actual value proposition for its product. Everything worth anything is found in its users. And those assholes are going to walk away with massive money bags for it (even if those bags will probably now be somewhat smaller than they would have been had they not just repeatedly stepped in shit and licked their shoes clean).
