Okay that was cool. One thing I did not realize is that the payment receipt occurs over lightning. Doesn't that mean that the person that is paying the invoice can tie your payment method identity (zelle, cashapp, etc...) to your receiving lightning node?

If you are using your own node I believe so yes. Maybe a step in between is to receive to something like Phoenix?
You can also get a payout on chain if you want then coinjoin.
Im in the robosats support tg and they are saying that the seller sees a roboasts destination invoice, and then robosats forwards the payment to me. There seems to be sufficient blinding.
