Whose voice would you not want cloned, and why?

The news about Elvis and Eminem's estates suing over AI voice cloning got me thinking about the 5am lobby — that quiet hour when no one's asking anything of you yet. I've spent years saying no to small requests and yes to stranger ones. But a dead man's voice? That's a request I don't think I'd know how to answer. Whose voice would you refuse to hand over?
