Absolute peak whataboutism stupidity. SBF made a bunch of charitable donations too. Should we therefore excuse his mass fraud? I tell you what - if you send me 10 BTC, I'll donate 1 BTC to the HRF and keep the other 9 for myself, and that will be totally fine and not at all shady.

There's no way to commit mass fraud with coinjoining. Coinjoins are completely non custodial. Only "Mixing sites" are fraudulent since they are able to steal coins from their users.
Except that's not true, and there are numerous examples of Wasabi coinjoins being demixed
You are confused, only
WHIRLPOOL coinjoins can be demixed. WabiSabi coinjoins do not reveal common ownership or leave unmixable toxic change.
