I would love to be optimistic about this, but I don't think the solution to this is going to be "creating a consistent set of standards and rules across multiple multinational companies". In my opinion, some of these games are bound to create toxic situations when playing with randoms. Take a game like League, where a single player that's underperforming can cause the entire team to lose. This dynamic is core to the game, and it's the root cause of toxicity. Compare that to a game like Counter Strike, where an underperformer might not drag their team down that much, and there is an option to kick the person from the team. The game is still winnable -- it will be harder, but it would not be impossible like in League. Also, surprised not to see Valve in this list. Dota 2 and Counter Strike are still pretty big titles, even if they haven't made a game in a while.
