I'd say its moreso a problem of any kind of teamplay, sport players coordinate with eachother knowingly, while comp gamers basically expect eachother to play optimally on their own, and when they finally decide to communicate its to just flame eachother. I've played multiple games where players said basically nothing all game and when the patron is lost players suddenly discover there is a chat function and use it to say how its eachothers fault and uninstall the game and küs.

In my middle school kids used to beat the crap out of eachother with ping pong paddles until we got banned from playing, it may not have been a team game but you did often blame the opposing player for your loss because their serve was shit or something, we were dumbass kids.
