Unfortunately "LE" around the world does not care for privacy. In fact, they put financial privacy on the same scale as money laundering. If you lost coins in CM, the best lesson you can take is that you should not trust a centralized service.
Sure. But a lot of honest people used ChipMixer also. They should have confiscated only the keys linked to fraud, carding, ransom attacks. Instead, they confiscated all money. And who knows... maybe they will send letters to Coinbase ,etc ... to return a lot of coins, or the $$$ equivalent, or all the accounts money! why not? most people will not afford a lawyer, or wait for years.
then they come to press and say how brave and smart they are, that they seized millions of dollars from frauds, etc.
I don't think that anyone honest should have anything to worry about if their coins are already out. In an ideal world, only direct evidence of major crimes linking coins to the things that you and the media have mentioned (fraud, ransomware, drugs, etc) would be the focus of the authorities who took chipmixer down. I doubt exchanges will ask users to return coins or anything like that. Similarly, I doubt that anyone who was honestly using the service will get anything back from these agencies.
