Earlier quoted context omitted.
This isn't about third party cookies, it's about cookies period - with the exceptions listed in the article. If you use your own analytics package, the chances are it will use cookies, so user permission will still be required. Log parsing isn't sufficient to get user-based statistics.
You can get user-based statistics without cookies with: (new Image()).src="http://your.tld/track.png?ua=" + encodeURIComponent(navigator.userAgent); and then parse your logs. Update: this is just an example, as ars notes the user agent is sent as a HTTP header. But screen resolution etc is not.
Third parties may wish to store information on the
equipment of a user, or gain access to information
already stored, for a number of purposes, ranging
from the legitimate (such as certain types of
cookies) to those involving unwarranted intrusion
into the private sphere (such as spyware or
viruses). It is therefore of paramount importance
that users be provided with clear and comprehensive
information when engaging in any activity which
could result in such storage or gaining of access.
The purpose of the directive is to be as broad as possible to cover collection of any type of information without express permission or "strictly necessary and legitimate purpose".[1] http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2...
