I believe nopara37 knew something like this would happen, and therefore accepted the trade-off of blocking UTXOs from illegal activities. From his point of view, he probably thinks that he made the right decision to protect himself, Wasabi, and its users.
I wouldn't compare Wasabi wallet with services like tornado.cash, first because they are not used for improving privacy for same coin, and second because coinjoin in not illegal anywhere.
Wasabi wallet didn't start blacklisting anything, unlike ethereum wallets like Metamask that uses Infura, and other fake dex exchanges like uniswamp, dydx, and others that are confirmed blacklisting and freezing coins.
