NB. I do not know the number of POP for deSEC but it is certainly more than 1.

BuddyNS "Astronaut" accounts are Anycast and offer DNSSEC.

BuddyNS enables DNSCurve for free accounts; none of these other providers even offer it.

Yes because DNSCurve is no good.

DNSCurve is abusable by local governments so ICANN has stated that the root servers will never implement DNSCurve.

https://security.stackexchange.com/questions/45770/if-dnssec...

This is an assertion attributed to a Namecoin talk at CCC, and it makes no sense: local governments already have practically absolute control over their TLDs. The reason DNSCurve isn't deploying is that DoH has sucked the wind out of its sails.
