Cloud flare even offers a CDN for npm libraries.
it feels like incapable "experts" are placed in position or authority for something like this to happen.
Why would anyone use a cloudflare js cdn for anything but a toy site? Those are bad decisions by developers.
They are, but that doesn't mean it's their fault when websites fail because LaLiga decided to block an entire ISP. That's pure victim blaming. "Oh, what did you expect when you rely on a third party and another company wields the power of blocking anything without a specific court order?"
Huh? It is their fault though. They chose to rely on a third party service that they don't own and had no mitigation for when it failed.
Sure using a different domain has come to being bad practice for security and performance reasons, nonetheless fetching libs from CDNs including cloudflare remains prevalent. Even if they would make a move that is slower than takedowns.
