Rather than putting real effort into this, I'm just going to say that Paul Vixie, the creator of DNS, advocates for using a local resolver (not your ISP's resolver), and DNSSEC. The internet is supposed to be decentralized, not centralized.
Cloudflare, Google, and all of these other centralized dns/ntp services are hazardous to our health.
I'm sure you're very knowledgable, but if Paul gives DNS advice, listen to him.
