TIL, thank you. Time to go tweak my pi-hole server...
Because "if it ain't broke, don't fix it." i'm not one of those users who want to endlessly tweak their ad blocker. i want to set it up, clicking as few checkboxes as necessary to get it going, and then leave it. However, (now) knowing that Cloudflare filters different only each of their servers, i'm incentivized to go tweak a number in the config (as opposed to researching the pros and cons of every possible provider, a detail i truly have no interest in pursuing).
The upside is there's no single entity receiving all your queries. The downside is there's no encryption (IIRC root servers do not support it), so your ISP sees your queries (but they don't receive them).
Since ISP know your identity, and all it takes is to (request and get) the DNS logs and ISP servitude for all sort of questionable information, you as an identity are giving away all sites domains you visit.

if you think a little creatively about how this information could be used by an organization that was created at the insistence of the United States Department of Homeland Security, then you're on the right track.
