I just explained how your design lets a payjoin sender could drain the receiver's wallet. Do some research before spreading misinformation: "In exchange for the privacy benefit, the sender has to pay more fees than a normal transaction. It is a con for the sender, but a pro for the receiver, since the receiver does not have to consolidate its coin later." - @nopara73 (coinventor of payjoin) https://nopara73.medium.com/pay-to-endpoint-56eb05d3cac6
