The article says (my emphasis):

> segregate the _cross-site_ scripting data

So if you "just want to quantify your traffic", use self-hosted Piwik (i.e. not cross-site), as many of us do already.

What's the advantage of third-party analytics over self-hosted ones (e.g. GA over Piwik), except for "someone else hosts it for me for free"?

Honest question. I'm not logging anything about my websites' visitors on principle, so I don't have insight into that area.
