Does anyone believe that Verisign and other operators of top level domains are not also doing data mining of the DNS queries they see?
Remember, when a DNS query hits a server it most often contains the full domain name being queried.
Because of caching of DNS information the top level domain servers are unlikely to see every query. But it's no great trick to do some statistical analysis to come up with a confidence level in the information derived from the queries that are received.
Root server operators have the same ability, albeit more dilute due to even more caching, to generate that kind of marketing data. The current crew of operators probably are not doing this, but there is nothing to prevent them from doing so in the future.
