iCloud Private Relay Subpoena
Has iCloud Private Relay ever been successfully subpoenaed for the original user IP / Apple Account behind a Private Relay Address?
iPhone 15, iOS 18
Only Apple would know that, and Apple doesn't hang out here and answer questions. And even if they did, I'm pretty sure that is one they will never answer, on advice of their lawyers...
Well, actually, I suppose not only Apple would know that, there is also the subject of that subpoena and whoever filed it in the courts. But the former would probably never admit to it, and the latter would probably require an Access to Information request, assuming one even knew who they were.
