Edit: by "he" I mean Javier Tebas.
Problem with that is that there's perfectly valid legal reasons to censor individual websites and people will absolutely block all of CloudFlare to get them to go away. In this case, the corpofascist copyright owners that happen to own Spain's legislature decided "well, then we'll have to have no Internet when there's a soccer game, then".
But there's plenty of other legal or moral reasons to block a website, as much as the EFF would disagree. At the very least, CloudFlare has a sterling track record with providing infrastructure to cybercriminals. Every DDoS service puts their sales pages on CloudFlare, because when you happen to have a low-orbit ion cannon[0], the easiest thing to use it on is other vendors of low-orbit ion cannons. Same with malware, because it's very easy to get your malware on a CloudFlare server and a pain in the ass for antimalware tools to block it.
[0] LOIC is a "consumer grade" DDoS tool used predominantly by trolls and activists on 4chan in the late 2000s. Probably not what the DDoS vendors are using.
