I remember this story and it missed the entire point.

The customer ( a casino) was using dubious actions in different countries which impacted Cloudflare's IP trust. Tldr: Cloudflare didn't want an IP ban in their IP's due to government regulation.

The fix was to bring their own IP which is an Enterprise feature, as they weren't allowed to use Cloudflare's IPs anymore.
