Stephen, 

It didn’t take me more than about 30 seconds of reading the linked article to get to the heart of the issue.

It has to do with whether something that requires consent is a necessary part of the service or transaction.

It has been clearly demonstrated that browsers do not have to provide DNS resolution (since they have not done so for about 25 years).

This means that requiring the user to use the browser’s selection of DNS resolver, and implementing a DNS forwarder in the browser, would not be covered by the general acceptance of the browser’s terms. In other words, an extra level of informed user consent would be required for GDPR, and not accepting that second set of terms should not prevent the use of the browser. Tying the two together would be a violation, at least as I understand it as explained by the link Jim provided.
