Why does it matter that it’s a recursive resolver? They mention this a lot but it seems like the decision would just as much apply to a non-recursive resolver.

I didn’t attempt find the ruling; perhaps the lawsuit was written in an odd way.

It is difficult to envision a "non-recursive DNS resolver" in public service. Recursion is the usual and customary way that DNS names are resolved by the leaf servers, because they are not authoritative for much of anything.

The most common configuration for non-recursive DNS servers is with forwarders. The DNS server accepts queries and simply forwards all of them upstream to another resolver, which... makes its own recursive queries.

It is simply not feasible to avoid having recursive resolvers in the chain of lookups. That's how things work with DNS.
