in theory. in practice, most coinjoins are very obvious on-chain, and some exchange customers are paying the price for it. taproot, cross-input aggregation, and less obvious coinjoin mechanisms will mitigate this in the future, but for now all i can say is, be careful of your proximity to exchanges and AML/KYC enforcing services when engaging in coinjoins.
When an exchange harms your privacy applying weird heuristic to your transaction before or (worst) after using them, just stop using it.
I started a thread on this exact fact: [PAXOS+COINJOIN]Your privacy is a threat to exchange business?#deletepaxos

people should absolutely "vote with their money" and leave such exchanges, if that's a viable option for them.

that doesn't address the larger issue though. we need to consider what people actually do by default. think about why the maker/taker fee model is so prevalent: because the vast majority of market participants are liquidity takers. further, there is zero indication that privacy is a priority for most of them. they will continue seeking out the highest liquidity exchanges, who all seem to be ratcheting up their AML standards one by one.

so while i agree with you, i don't think that's a viable solution long term. privacy advocates will just have less and less services at their disposal, with worse and worse liquidity. what we need are better coinjoin solutions so that we can slip through unnoticed with the the rest of the masses---so we aren't at a constant disadvantage re liquidity. this will take some time.....probably years.

wasabi wallet was groundbreaking as a first step, but its coinjoin implementation obviously puts its users at a great disadvantage re existing blockchain analysis heuristics. that's a problem we can't afford to ignore.
