Agree with the article. I think we generally underestimate the privacy-destroying power of the UUID: a single random-looking number can track absolutely anything. Digital systems should require auth via public-key crypto rather than global IDs but keys can be correlated too. Whenever possible we should build systems with technical and economic incentives to preserve privacy, but I wish we had better ways to do that.
