If they did, then that I believe, would make sense for WasabiWallet to accept the trade-offs to protect its users.
They are making the trade off to protect their profits, not their users.
That's merely part of it. They want to protect their own reputation too, and the user's trust, or what's left of that trust. Plus Wasabi isn't just a CoinJoin service, it's also a wallet where people hold some of their Bitcoins.
