Author seems to have buried the lede, because the real meat of the problem is described only in the last third of post. It's not about technology, it's about the scope and intent. Or if we had to distill the opening premise of the post into a single word response:

> All web analytics need to somehow track individual users.

Suitably anonymised, unintrusive first-party statistical analytics are fine. Stalking users is not.
