For what it's worth (very little), I stopped by Wasabi's booth at the BTC conference in Miami Beach today and spoke to the guy manning it (my first stop after they opened the doors).  The guy there was NOT "nopara73". 

I asked him about this whole issue of Wasabi not allowing certain UTXOs to be used in their CoinJoin service.  He gave me a "plausible" response, essentially saying that the banned UTXOs would be those directly linked to wrongdoing (my wording), like for big BTC thefts, etc.  He said it would be uncommon (again, my wording not his).  Like I wrote above" "plausible"...  So, I really cannot knowledgeably comment any further, just don't know, but the fact that they are doing this is NOT GOOD, IMO.

I did not feel like grilling the guy any further as I had only today to see the show with lots to see & do.
