@kruw thanks I'll ask other questions after analysing your replies. It doesn't look like zkSNACKs are keeping info which links users after mixes but it's about trusting what they're saying.
There's no trust in zkSNACKs necessary - Wasabi is completely open source so you can verify for yourself that no identifiable data is ever sent to any third parties, including coinjoin coordinators such as zkSNACKs.
Wasabi wallet being marketed as a privacy solution while simultaneously funding blockchain analysis is contradicting. I haven't seen data they're doing excessive bad things. Analysing incoming coins for
naughty status isn't the biggest crime if it's designed to stop crime. If my wallet's hacked coins were sent to any address on its way to Wasabi for mixing I'd be happy if they succeeded in stopping coinjoins so I'm not getting why that makes people upset.
Yeah, it's quite strange to see o_e_l_e_o be so passionately furious at the idea of a business refusing to make stolen money private that he would misdirect that anger at an open source project that allows anyone to run a competing business. If he hates zkSNACKs so much, why isn't he simply running his own Wasabi coordinator by copying and pasting their open source code and making them go out of business by offering their service for free instead of charging any fees?
Which data's being stored by zkSNACKs in this transaction if I'm using Wasabi wallet.
o_e_l_e_o sends 0.1 btc to arabspaceship123
arabspaceship123 sends 0.1 btc to Wasabi wallet
Wasabi wallet sends mixed 0.1 btc to arabspaceship123
arabspaceship123 sends 0.05 btc to o_e_l_e_o
arabspaceship123 sends 0.05 btc to theymos
The data stored by zkSNACKs is the exact same data that is stored on everyone else's full node when these transactions are confirmed in blocks. zkSNACKs has no knowledge about who owns coins that have been mixed.
