Nostr has never promised privacy.  I often try to push for more privacy in nostr, but it's often an unpopular opinion.  "tracking" is pretty standard, I am told.  It is, but there should be an alternative.  NIP-04 goes a long way, but it would be even better if it was transpoted in a more private way, over HTTP or with privacy respecting sites or relays. 

 Why is it unpopular? Is it not possible? And if it is why aren't we given the option at least?  

 I dont track people, because I want to build software that I'd like to use myself, and that I can let my friends use.  However others normalize tracking because they can get a free service, or make profit by selling user data to a 3rd party.  So there's different views, and different incentives.
