What do you mean "combining UTXOs outside of a Wasabi coinjoin", lol?  There is no such thing because WabiSabi allows you to combine your UTXOs INSIDE COINJOINS, which prevents revealing common input ownership.


You are wrong:  tx0 is stopping them.  Since tx0 is a self spend instead of a coinjoin, that means it reveals all inputs are owned by one person, and reveals toxic change that belongs to that person.


It is a flaw in the Whirlpool coinjoin protocol because tx0 reveals multiple addresses belong to the same user by creating unmixed change, and reveals common input ownership because it is a self-spend transaction instead of a coinjoin.  WabiSabi coinjoins make it so no two addresses are ever linked to each other (for anyone except the largest whale in the round).


So why are you telling people to use Samourai's Whirlpool which reuses addresses?  I already provided you proof of their address reuse happening in multiple cases:



The deeply unethical behavior (sock puppeting) you are referring to was done by Samourai's developer, not Wasabi - https://nopara73.medium.com/samouraileaks-samouraidevs-sockpuppet-exposed-7ce654b92c0b
