The c&c/botnet designation would seem to be new though.
Looking forward to when Google Safe Browsing adds their domains as unsafe, as that ripples to Chrome and Firefox users.
This is notably not a change to how 1.1.1.1 works, it’s specifically their filtered resolution product.
The current situation is due to Cloudflare flagging archive.today's domains for malicious activity, Cloudflare actually still resolves the domains on their normal 1.1.1.1 DNS, but 1.1.1.2 ("No Malware") now refuses. Exactly why they decided to flag their domains now, over a month after the denial-of-service accusations came out, is unclear, maybe someone here has more information.

Ditto for their other domains like archive.is and archive.ph
Example DoH request:
$ curl -s "https://1.1.1.2/dns-query?name=archive.is&type=A" -H "accept: application/dns-json"
{"Status":0,"TC":false,"RD":true,"RA":true,"AD":false,"CD":false,"Question":[{"name":"archive.is","type":1}],"Answer":[{"name":"archive.is","type":1,"TTL":60,"data":"0.0.0.0"}],"Comment":["EDE(16): Censored"]}
