There's one thing that props up EA despite their fuckups and that's the amount of people buying their soccer game.
It's the only way to play a soccer game with licensed clubs, which makes it a monopolized market.
To kill EA as a corporation - you have to change that. There just have to be alternative soccer games with licenses for the main European leagues.
Otherwise, they'll just keep buying up anything they can with the FIFA money.
FIFA is not only one; you need also tackle NHL and NBA
