They did a great job with their CoinJoin client but the war on privacy (on privacy-preserving developers, really) is something that scares everybody, and even then they made the move. However, look at what happened with other wallets after the Samourai devs were arrested: they removed the coinjoin functionality immediately, they didn't desabled it but removed the code enterely. Well Trezor didn't do that! The CoinJoin feature is still there and you can still use it. Or even better, you can take that code to create your own client which, by the way, is 99% of the code required (the CoinJoin coordinator is just about the 1%).
