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.)

Or simply some politician traveled to Canada and said to his aide "Why can't we do that as well?"
