I acknowledge that some Wasabi coinjoins are successful, and provide decent privacy. What I don't see you seem concerned is the coinjoins which appear to involve reuse of addresses. The only thing you do is deny they come from Wasabi, despite all the arguments put forth by numerous Twitter users.

Everyone already knows you shouldn't reuse addresses, it's in the Bitcoin whitepaper:

As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.
