I wouldn't blacklist.

There are so many better privacy projects out there that are not succumbing to these unknown "regulatory pressures" that Wasabi is claiming are being forced on them and them alone (despite them having the lowest volume of the three main coinjoin techniques, lower volume than many mixers, lower volume than many DEXs, and far lower volume than privacy coins). If projects such as Samourai, JoinMarket, ChipMixer, Bisq, LocalCryptos, Monero, and anything else which gives users as good or better privacy than Wasabi can continue unencumbered, then Wasabi can too. They simply choose not to.
