So how is telling the victims of who had their funds confiscated and data leaked to the government that "Mixers are not trustless nor non-custodial" helpful once they've already lost everything?...
Awful. But that's the price you have to pay when you trust your coins to some stranger. You may never get them back. As for data leaks, I have never used a mixer that was known to be a government honeypot, neither do I know of any such.
Wanna tell us how it is to tell someone he isn't worthy of having his privacy protected, while at the same time pretending to be the ultimate solution to Bitcoin's fungibility?
