Yes, I have a PhD in cryptography and designed two of the first privacy-preserving extensions to Bitcoin. Bitcoin provides pseudonymity. If no other information can be inferred about a transaction from other sources, users may be able to protect their privacy. In practice this is extremely challenging, and the information leakage this post is discussing is highly unnecessary, and a weakness of Bitcoin.
