It's ridiculous and wrong what LaLiga does. But it's also a weakeup call to consider ditching cloudflare's centralization.
The only reason this happens is because Cloudflare's centralization makes precise censorship impossible. That's bad in this particular case (as it results in over-broad censorship), but good in general, as it makes censorship harder.
Without Cloudflare, you can censor whatever you want. If you have the support of an (undemocratic) government on your side, you can even DeDoS them, making sure that information critical of you cannot see the light of day.
Cloudflare has nothing to do with it. Actually you should further insist on using Cloudflare in Spain to increase the collateral cost of this ridiculous government decision as much as possible. Make it so not a single website works during football, and see if the government changes their tune.
I agree with this take (that it’s a wake up call). Makes one question their entire app design and if using Cloudflare is “good enough” for managing CDN, tunnels, etc. for their apps.
The companies relying on cloudflare won't be in Spain. If you buy a GPS tracker by a Canadian company, developed in India, manufactured in China, they are unlikely to know, even it they cared, that a single country that accounts for a tiny percentage of their sales breaks fundamental internet infrastructure on the regular "because fútbol y dinero".
And when purchasing a product, there's no "bill of materials" telling you about the services it relies on, beyond "internet connection" at best.
