I am hardly surprised
So many web sites these days include heaps of javascript, trackers, adverts, etc, which are hosted elsewhere. All of these collect information. One of the worst web sites I have found for this is W3 Schools. I understand that web sites want to track readers or viewers or participants. I understand the 'need' for adverts for otherwise free web sites in quite a few (most?) cases. But just how many of these things does a single web site need? Why does a web site need multiple traffic analysis scripts? Before anyone answers, I already know the answer. My question is based on actual 'need' not 'sometimes it is better'.
The mantra 'be careful where you browse to' has become meaningless, when apparently 'safe' web sites are full of information gathering code hosted on sites that I have never directly visited.
The tentacles of Google are everywhere, and it would be extremely naive to think or suggest that all this information is not collated. We probably all have a Google ID somewhere.
