one extra thing to mention is he role of Telefonica here. they are both an ISP that needs to apply the blocks, but also its subsidiary "Telefonica Audiovisual", who holds rights for the football, is a plaintiff.
one of the claims were that this is somewhat a procedural fraud since the plaintiff (Telefonica Audiovisual) and the defendant (Telefonica Spain) is technically the same thing. the order was granted after the defendants admitted, and therefore there wasn't any hearing with CF.
What’s even more confusing is how can a Spanish court just order a legitimately registered taxpaying Spanish business (assuming cloudflare has done so) to shut down their services without even a chance to provide an argument?
They didn't order Cloudflare to shut down, they ordered ISPs to block any IP LaLiga claims is hosting pirated football. The president of LaLiga "Javier Tebas" also called Cloudflare a criminal organisation for enabling and making a profit off anything including child pornography (without any evidence of this, of course, just his word).
Now, there is also a conflict of interest, because Telefonica (the main telecom provider here, think Deutsche Telekom in germany or any formerly-public ISP) is also a rights holder to some football, meaning their interest is to block everything instead of their internet users, who suddently can't work on Github, visit Twitter or many other large sites; or even can't buy in many places online because Redsys (the largest payment processor here) also uses Cloudflare to protect their infra, and Cloudflare IPs were being blocked indiscriminately. All of this while being able to force other ISPs to block those IP ranges too, and without any possible recourse by either Cloudflare or the sites themselves, which according to Tebas "are only used by 4 nerds who like to complain".
