Although the comment was sarcastic in nature, let's say it wasn't. We don't know which blockchain analysis company Wasabi has partnered with and there are several of them. What if the bitcoins are considered free of taint by some institutions and centralized exchanges based on the info they are given by one anal company, but at the same time a different anal company considers some of those coins as dirty and send out different signals to their partners? Unless all blockchain analysis companies cooperate in terms of what is tainted and what isn't, I would expect that they show different results and taint scores.
