> What is the contrast here? I don't think I'm making a contrast. I originally said that bolt12 is bad for privacy if you reuse it, because it involves reusing a pubkey over and over again. After a correction from Matt, I slightly revise my point: it's still true that bolt12 is bad for privacy if you reuse it, but that's not because it involves reusing a pubkey over and over (though it does), it's because you're reusing *anything.* For good privacy, never reuse any data across two different services.
