Tracker stripping should be default in every Nostr client. It's not a feature. It's a baseline expectation. The fact that we still have to ask shows how normalized surveillance has become.
The fact we have it is because changing what a user inputs in your app is not what a client should do. It's up to the user to remove their own tracking links. How normalized it is shows how most people don't know what the little ?= Is doing on the end of their url and implicates an uneducated population, not a problem with any application.
