I claimed Samourai is a scam, and explained the reason why: it markets itself as a privacy wallet while it has very bad privacy. People who use it are promised privacy, but they don't get it. Samourai users are the victims of the Samourai scam. In contrast, zkSNACKs is not lying about its blacklisting. No dishonesty there, therefore the definition as a scam does not apply.
I agree with the sentiment that Samourai is very misleading in that at first sight it appears you get anonymous mixing with or without full node, but then it turns out that if you don't run one, you lose all privacy by doing one of the worst things you could do; leaking your
xpub.
Sure, zkSNACKs openly confesses to blacklist, but it also still claims to be a privacy wallet. While working with chainalysis. How doesn't this immediately sound like an oxymoron?
I wouldn't say either of them are a 'scam' in that they don't steal your money, but Wasabi sends your information to Chainalysis and Samourai deanonymizes you if you don't buy their node, so they're both going against their main proposed selling point (privacy) in a rather similar way. You could argue that Samourai holds the xpubs themselves, while you guys pass the info further right away, however I don't trust Samourai to be government- and three-letter-agency-secure if they come knocking.
