Whois is an interesting case. It's a cornerstone of the open internet. In these times of "fake news," knowing who owns a domain is even more important. On the other hand, whois privacy has been an add-on feature for which domain registrars charge extra for years. I guess we'll see how this shakes out.
Frankly, the original internet and the technologies and institutions that grew out of it were based on gentlemen's agreement and the assumption that everyone was who they said they were and could be trusted. That is very much not the case anymore, however, and the wear shows more and more every day. Unfortunately, I'm not sure that there is a way to fix it in a safe and secure manner that isn't also authoritarian to its core.
