It's going to be very hard to prove/disprove that without going too technical about it, won't it? Can someone, preferably from people who actually use Samourai Whirlpool, to ELI-5?
You want to coinjoin 0.052 BTC. Whirlpool creates five outputs of 0.01 BTC, which are coinjoined separately. It also creates a change output of 0.002 BTC. The change output is sent to a separate account, precisely to keep it separate from your coinjoined outputs. It is called toxic or doxic change since it is not coinjoined.
This is done deliberately to keep your coinjoin outputs of a standardized size (4 sizes you can choose from) and completely fungible. Samourai and Sparrow wallets prevent you from spending this change alongside coinjoined outputs. You can then spend or dispose of this change in a variety of ways:
https://bitcoiner.guide/doxxic/Kruw likes to misrepresent this very deliberate design choice as some kind of critical flaw, either because he simply does not understand how Whirlpool works, or because he has no issues lying about his competition.
