What do you expect these companies to do
Not exist in the first place!
...
What should really happen is that blockchain analysis companies go bust and disappear. If we all stopped using centralized exchanges and used bitcoin properly peer to peer as it was designed, that removes a big chunk of their cash flow...
But these aren't very realistic outcomes in real life. If Chainalysis were to fold tomorrow, you can bet there'd be at least a handful of similar entities vying for their old contracts & market share.
With the justice case US vs. Sterlingov (the mixer Bitcoin Fog), since their software is not accurate, the defense requested the Chainalysis’ source code to be audited.
They don't like this idea! Guess why? It's going to put their business at risk.
The code should absolutely be auditable... I agree with the overall sentiment in this thread that its ridiculous to put someone behind bars for what is potentially a very long time without thorough "due process." If Sterlingov was indeed just a user of Bitcoin Fog then it would be an egregious miscarriage of justice to sentence him based on potentially faulty analysis.
