I have no idea what their intentions are, but if they believe they can “identify people who share PDFs” then they are fools. How is “someone must have stolen it off my computer” not an ironclad defense against this?
I was wondering that for years why they don’t do it. Sad that the article doesn’r state how it’s implemented. But if you have two pdfs that should be the same you probably can get the difference.
