The "privacy to users"seemed odd to me too. On thinking about it I wonder is it poorly phrased and the point they are getting at is to do with the fact that the wallet is unencrypted by default currently. Should have said something like "protection to users" rather than "privacy". Bit of a leap to make perhaps?
I recieved an answer.
We have strongly considered Bitcoin as a payment option and did some testing.
However, we are not convinced that the current Bitcoin system offers enough
privacy to users and the technical implementation of the official client is not
ready for prime time for online stores yet in our oppinion.
We'll keep an eye on it.
Visa, Mastercard and paypal offer more privacy to the consumer?
