I think burns/jokes about Cloudflare are missing the point. It's not about Cloudflare, it's about the millions of people in Spain who couldn't access a plethora of legitimate, unrelated websites and services because of the block. The block included things like Redsys, a major payments processor used by tons of ecommerce sites in Spain.
Piracy or not, you shouldn't be able to get away with this kind of collateral damage, blocking an entire population from accessing a far greater number legitimate websites.
And while I do understand their problems with piracy, LaLiga's view on the matter has always been so over-the-top and reminiscent of the false logic the record companies did in the early 2000s: LaLiga believe (or at least say, all the time) that every euro's worth of football that is pirated is a euro that has been stolen from them; that if piracy didn't exist, they would have that much more money. It's simply not the case. It's a hugely outdated viewpoint, and they shouldn't be able to cause damage to the public because of their adherence to it.
