Your standpoint is, that this has nothing to do with the ISP's DNS resolver or selling DNS data. I have no explanation why an ISP should apply better privacy protections to their customers DNS data compared to the customers network traffic because both enable a significant monitoring of the users' online activities. Do you have an explanation for this? Erik
