To be clear people are mad about that because large portions of the legitimate internet go dark when football is on because they're running on a virtual server that happens to share an IP with another virtual server which is hosting pirated football.
You and I have no idea how often perfectly legal things we rely enjoy or rely on would go offline during football matches because it doesn't happen to us.
I don't think you get it. They block Cloudfare IPs so services using Cloudfare become unreachable. I don't live in Spain anymore, but I have friends that can't access their university website while a soccer match is ongoing.
This shows the risks of centralizing internet access
