I was wondering: Why does the EC believe that the resolvers users currently rely on (e.g. provided by their ISP) provide “low-quality”? Are there any studies about this?
One possible response is that the people who write these statements don't know what they are talking about. But of course, I cannot believe that. So, another possible response: in Brussels, they see that some users move away from the IAP resolver to a public resolver, so there is probably a reason for that. (Unfortunately, DNS4EU may not address this reason.)
DNS resolutiuon is, economically speaking, a wasteland - users don't pay for queries so the infrastructure that handles queries is bundled up with other services, which is what your ISP does. But users don't generally decide on an IUSP based on the quality of that ISP’s DNS so the DNS department is part of the cost part of the business, not a revenue generator, so it gets little attention. Some ISPs have attempted to change this by monetising queries (selling the query logs) or changing responses (NXDOMAIN substitution) but such efforts has been generally regarded with extreme disfavor. So the DNS resolution environment limps along.
