Phoenix panic-exited the US after the Samourai arrest. We don't have any details about reasons for this. It looks like a knee-jerk reaction but they might have their own reasons. Samourai wasn't just a wallet - their coinjoin service allowed mixing of UTXOs to improve privacy and the owners almost bragged, in tweets, about how criminals could be using their services. Still what was done to them is an infringement on freedom of speech rights, regardless of how unwise they were.
Point is. There is no outright ban. But we did see WoS leave last year too, so it's definitely getting harder to use freedom money and not be controlled and tracked in our every move. As expected though. We will persevere and find new ways!
