I know that, and you know that, but I showed this article to my wife (who is a casual computer user), and while she understood the difference when explained, she said that as a non-techie, she interpreted the title differently. If you hash my data, and take action based on that hash, then you have looked at the data, however cursory or algorithmic it may have been.
FWIW, I had this same discussion on reddit, where it devolved instantly into name-calling. HN is much more civil. Thanks for that.
