Comment (by cypherpunks):
Q. How to make sure my computer/phone can't talk to Cloudflare by OS
level?
A.
A1 - Firewall
iptables/nft & DROP rules
A2 - DNS lookup
If the response IP is owned by Cloudflare(ASN), return 127.0.0.1, 0.0.0.0,
or NXDOMAIN.
(there are famous linux package which allows you to do so)
Do both, and CF can't talk to you.
