If developer flags txns that come to his pool, and the role of the coordinator is to have the biggest pool possible, then even if coordinator is foss there is still a control of utxos that come into it. Why do they flag income tx that they think at bad or whatever? Yes I can run your own coordinator but that defeats the purpose of being in the biggest pool possible. Are you suggesting that I run my own coordinator and mix with myself? That is why sparrow wallet is using whirlpool and it’s pools and not their own. Because one want to hide and stay hidden in the biggest pool available. So ANYONE by themselves defeats the purpose of staying hidden.
