When did I say that it does? The randomness of the data is entirely down to the implementation. Personally I'd trust the random data supplied by a third party web service less than the pseudo-random data that the software on my local machine produces. Especially if you mix in data from a TPM, especially if you mix in data from an Entropy Key as well.
