By the logic of this removal also maybe Bustabit should be banned because in their site they advertise mixing with just different words:

Who do they offer privacy from? Other players, random internet users, or governments? I assume the casino logs all transactions and winnings.
Any centralized service can claim to keep no logs while in fact they do. So logs or not is kinda besides the point.
The thing here is if you for example wanted to deposit to an exchange, companies like Coinbase tend to follow the trail of coins and if your transactions are tied to a "tainted" address (which may include casinos) then there's a high chance you might be asked questions or they might even close your account which could cause troubles. So for users feeling insecure depositing or withdrawing coins to a casino if they get their coins from an exchange like Coinbase then some basic mixing kinda helps ease the stress of potentially being caught and having your trade account shut down.
But as a side effect this can also be utilized with people that don't have as pure intentions as avoiding their trade accounts shut down. It could also be indirectly used for people wanting too hide their tainted coins involved in trafficking and whatnot. You can never know really. With bitcoin being traceable these problems arise everywhere. You may be depositing coins to have some fun and if you end up winning and withdrawing profits, by the governments standards you could be partaking in a "money laundering operation".
