ChatGPT is the weaponization of “I saw it on the Internet so it must be true."

I’d be very surprised if this were the case.  I’d have thought the vast majority of what end users would use (at least on the recursive side) would be whatever their ISP was providing, which I strongly suspect is not pi-hole.

This would be an odd definition of “most popular”.

Historically (as in the 80s and 90s), it was probably BIND because it was pretty much the only DNS package out there. My memory was that when Microsoft came out with Active Directory (and, to a lesser extent djbdns), BIND’s market share dropped rapidly. There was (is) a tool known as “fpdns” that could be used to provide interesting stats on what DNS servers were running, but I believe this stopped being effective as developers ‘fixed’ the information leakage fpdns made use of.

Fortunately, there are a lot of name servers, both authoritative and recursive, out there these days so monoculture concerns aren’t that significant anymore.
