Yes, because it's a scam. No privacy, just marketing. Whirlpool is not on the same level. Unlike Wasabi or JoinMarket, it isn't trustless. Using them you trust a third party with your privacy.
I never said it's a scam, for saying that you would need to show some proof, and I didn't hear a single case of anyone in forum getting scammed by using Samourai wallet.
Should I also consider Wasabi wallet to be a scam just because it's ignoring to mix some coins?
This is a fundamental privacy leak, which just makes the two wallet not even comparable. However the problems did not end here, I think they can be deanonymized by other means, too, but any discussion comparing the two should.
I never uses Samourai, and I know they have some privacy issues, but at least they are not blocking any addresses from mixing.
Attacking each other in current situation is just waste of time in my opinion.
