Are we sure? This seems to tell us they are doing traffic analysis and so forth. It doesn't seem to say much about cryptanalytic capabilities. For all we know they could have all the crypto in the bag but need analysis to identify talkers due to people being exceedingly careful about the message content. "Blue hen rides over the book on the left side when the sun is low. Do you copy?" Now if someone leaked all the secret crypto capabilities docs out in public, or someone else got in trouble solely from what they properly encrypted, then we'd know whether or not the crypto works.
