It's going on a tangent, but one naive take which continues to amuse me when it comes up is community/third party servers and policing of cheating. As though delegating that responsibility is the goal or that it would scale to handle the size of modern playerbases including the ratio of admins to players to be able to monitor and respond to (alleged) cheaters
But as gaming has grown and become more mainstream, the ratio of enthusiasts who are willing to admin to casual players who don't has changed. Server sizes have changed over time with smaller games like 5v5 becoming way more common.
