Wasabi cannot sell any data to chain analysis companies because Wasabi does not collect any data. By default, your IP address is masked by Tor and your wallet addresses are never linked to each other thanks to client side block filters.

The reason Finch is lying about Wasabi is because, unlike Samourai, Wasabi's coordinator code is open source, so ANYONE can run their own and outcompete the closed source monopoly Samourai tried to create out of the Bitcoin privacy industry.
