The ISPs are compelled by judicial order to take down whatever LaLiga tells them to, and LaLiga is telling them to block the entire IP range. They can’t not do it.

From vague recollections of previous times this came up, I think this is downstream of the providers getting blocked refusing to cooperate though?

I know when eSNI / ECH came out, Cloudflare at least made a point of taking about plans to use it to frustrate targeted blocks in hopes that governments would be unwilling to respond by escalating to blanket IP blocks.
