The fact they had everyone's xpub (except those who self hosted their dojo) means the feds have them now. All past and future addresses in samourai wallets are now known to the feds, and all the mixing was for naught. Also, the feds now own (by theft) one of the most capable analytics tools supercharged by one of the most complete bitcoin address databases.

Imagine all the poor sons of bitches that turned Tor off in the wallet software.
Ooof. But given most of the time it was KYC coin on the input, their government ID mugshot is now plastered on every address, in and out.
*sigh* You can't blame the users, I guess. I did the same thing in ignorance, before the govt could even spell BTC.
I blame:
* Samourai for arrogantly marketing their flawed ideas as "privacy tools"
* "Privacy" Influencers who ran cover and talked about Samourai as if they were a legitimate option.
* Fucking VCs drawing outsized funding towards the biggest assholes in bitcoin.
* The government, ofc, but they were gonna do what they were gonna do anyways.
I mainly blame Samourai. It was always suspect why they take your xpub and why they ran closed source analytics. They could have designed it to not require xpubs. Wasabi doesn't need them
