Samourai Wallet by default collects the xpubs of their users (past, present and future financial transactions) thus they provide zero privacy against themselves (and hackers and governments.)
In contrast with Wasabi, wherein to mix, you need to pass the legal-UTXO test? Disgrace. At least in Samourai you can run your own node and avoid handing out your master public key if that's the only problem; you're sure you're having your outputs mixed.
Should I also consider Wasabi wallet to be a scam just because it's ignoring to mix some coins?
Beyond that, they're working with chain analysis companies, treating bitcoin as non-fungible while that's the promising point of their project. It's confirmed that they did this voluntarily to
protect their operation to make money. Whoever mixes with their coordinator pays for their monitoring. Completely untrustworthy individuals.
