Bear in mind that your sense of justice derives from a country that uses a death penalty, has a legal system based on private jails, has non-existent consumer protection, has non-existent privacy protection, etc. US is not a Western country but a case of its own. Whereas in EU, there is such thing as the legally protected right to work and to compete as an athlete. Because Valve has propagated its game to be used as a platform in professional sports, it cannot use arbitrary methods to govern usage of the game. The Finnish court will most likely take this as a case of right to work and compete as a professional athlete, which cannot be restricted by arbitrary punishments by Valve. The argument that Valve's terms say this or that, is not relevant, because the terms need to be in compliance with law and if they are not, as they clearly are not, they are waved aside by the court.
