Blocking cloudflare is about as useful as a screen door on a submarine. Unless they start blocking IPs like the great firewall of china blocking any DNS is kinda pointless. Unless maybe if the domain’s primary name servers are cloudflare but I can’t seeing any site doing nefarious things using cloudflare. Run your own DNS resolver on a VPS somewhere besides Italy.

My worry is the internet starts getting terribly segmented and not interconnected. That would be more of an issue.
