Most streaming platforms actually put a lot of effort into combating live soccer broadcast piracy, more than a lot of other types of content. European soccer in is massively popular globally, as is the World Cup. Thus piracy of it is massive and global as well, and it gives the big leagues and competitions a lot of leverage. Most platforms try hard to counter soccer piracy, generally without waiting for a complaint or takedown request, and often using active methods like doing automated content detection on livestreams. The platforms simply have more to lose by poor enforcement of a huge soccer event than most anything else, including anything from Hollywood.
