What is the point working with them then. Or with a Third Party who works with Blockchain Analysis. Same thing anyway. You indirectly willingly collaborate with Blockchain Analysis tools. If you say their attempted Blockchain Analysis is a guaranteed dead end then you either knowingly lie to them and are deceitful giving them only the impression they are doing something or you are lying to us by giving us only the impression the Transactions we make are fully Private.
Wasabi is not "working with chain analysis" or "willingly collaborating with blockchain analysis tools". Your data is always completely protected from being leaked to any third parties by the open source client, there's no data that blockchain analysis can gain when you use Wasabi.
