Any service can share its operations with an adversary. That's a risk. If you don't understand that, then you should prefer Digicash to Bitcoin as it's more anonymous, confirms transactions instantly and does not need any stupid mining. System that flings around my wallet contents does not leave a trace of that activity on the blockchain. Meaning of every transaction is known only to transacting parties, but not to anyone else. That's the big difference from any shared wallet, where operator sees the meaning of all transactions going through it.
