"I think his point is: isn't that a bogus thing for Uber to claim? That it can't release documents because of someone else's fifth amendment privilege? " This is generally correct. The privilege is personal, you cannot assert it on behalf of other people. (not to mention you can't assert it to prevent someone else from incriminating you. IE you can't assert it to prevent your friend from giving evidence against you, even about something you said :P)
