Spain's government is made up of spineless dinosaurs. So the official soccer diffusion corps bought the courts and sued all the ISPs to force them to block all the soccer piracy sites during a match.

Did that work? Hell no, piracy sites just moved elsewhere. But big soccer is slowly ruining the internet and all the EU governments are letting it happen
