And every time they are sued for facilitating piracy, instead of letting the case to proceed to trial, they settle out of court.

Other than that, the legal situation on Spain is pretty dire for LaLiga. The Supreme Court already ruled in Spain that, as per the current writing of the law, football transmissions are _not_ works subject to copyright as they're not works of "art, literature and science": https://www.poderjudicial.es/cgpj/ca/Poder-Judicial/Tribunal...
So it's likely that, if LaLiga sued Cloudflare or they made them party on any actual litigation, Cloudflare would defend themselves and possibly win. Therefore... they just don't sue them, only sue ISPs that have an incentive to just comply to any LaLiga request (as.. legal compliance and collaboration is one of the requirements for being able to buy rights to LaLiga matches in Spain. Yeah, no kidding, you can look it up in their public documentation).
Well, I lie. In a legal twist, they ended up suing Cloudflare for "participation in criminal activities", but not through the same avenue they sued the ISPs on (penal vs commerce court), with some interesting twists as accusations of "facilitating services to avoid the execution of a court order" - which doesn't make a lot of sense, as they're not even direct parties to that court order and they were denied taking part on it. https://okdiario.com/economia/empresas/justicia-imputa-ceo-c...
