AFAIK wasabi hires the service of a chain analysis company because they want to know how much risk they could face by mixing a coin. In that case the CA gives them info (some "gambling/porn/russian" thing) meaning that they don't give CA any info that it doesn't already have. No collaboration here.

However, wasabi has to pay for that unethical service what helps the CA company to survive.

It's clearly a case of cowardly, a decision taken not by force but for fear to be linked with high profile crimes. However, it is much easier to be brave when not skin in the game.
