That a sports league was empowered by the courts to do this in first place is buck wild to me. I live in America, so it's not like I'm unaccustomed to the government giving preferential treatment to corporations but I cannot fathom a court allowing the NFL to tell ISPs to block IPs across the entire country.
America produces many things more valuable than the NFL, is the difference. LaLiga is presently the single most valuable brand in Spain. When e.g. Google asks low-polarization parts of the government for things, it frequently gets them.
