A real example of privacy by design is duckduckgo's hidden service since it cannot, by nature, know who is using it.
I found most of the courses of action suggested by the article to be privacy by policy, which is laudable but it aint privacy by design.
I agree that for even better privacy, i.e. to protect against us being ordered to keep data in the future, you should search via Tor, reject cookies, etc etc.
