It’s too early to know what will be built in the future, but I would hope that client that tried to violate user trust, i.e., creating accounts where the nsec is not accessible, or selling user data, etc. would be quickly abandoned. Right now, we are in a place where the development happens out in the open. We know who operates our relays and builds our apps. They’re part of this community and we can call them out if they do something we don’t agree with. I don’t think anything like this has ever been attempted before.
