Success! @Quad9DNS' goals is to raise global standards of privacy in recursive DNS, and the first recursive DNS provider has stepped up to match our GDPR-compliant privacy standards! Meet Quad101, from Taiwan's Network Information Center!

As suggested by RFC2182, you should always use multiple DNS servers, on separate networks. That applies to recursive just as much as authoritative. But you shouldn't compromise on the privacy of your secondary, else you'll leak information without knowing it.
That's why it's so important that there's now another recursive resolver that's not collecting and monetizing user data (IP address/query pairs)... It allows you to use @Quad9DNS _and a separate secondary_ without compromising your privacy standards. I hope more will follow suit!
