Magic Transit (bring your own ASN), classic website DDoS protection (above the Business $200 tier, which has low, undisclosed data limits in regions like New Zealand) and ilk all require interacting with the sales rep, and unless your paying 5 figures a month they are disinterested.
There is a whole market out there between $300 to $2000 a month that Cloudflare could tap without making new infrastructure but is actively being ignored.
