I'm trying to understand the full scope of it, because I keep reading about how many websites don't work, and developer tooling that doesn't work, but then I sit here with a Spanish ISP and can only notice one going offline during games (Docker Hub), everything else I use on a daily basis keeps working. So I'm not downplaying, I'm trying to understand if the difference is truly so large between different ISPs, or if people just rely on completely different tooling, and if so, what are they using exactly?

Yes, I agree that it sucks and is terrible that the football league has so much power of internet infrastructure, especially when we're supposed to have free access to internet, that's in our constitution, and Spain also agreed as such when entering EU too, and many other reasons. That's a larger legal battle, one I'm personally not involved in, but I could take the time to actually understand what happens practically and the full scope, so I can at least note down exactly what went down at what time, so I can keep sending complaints about it.

But to truly understand, gather evidence and having any sort of chance of actually affecting this, you need to understand the full scope of it, outside of the piracy streams, the stuff that is getting blocked that shouldn't. A year ago I noticed a lot of that happening, but today not so much, so clearly it's different today, but still important to gather the full picture before you jump to conclusions.
