Surprising someone as experienced in the web would post a rant like this when not only do Facebook, Google and other large/"webscale" sites, but also much smaller ones that participate in ad networks. When I worked at Glam Media we were given a presentation on the ecosystem related to our ad networks and let me tell you the presenter (a VP or C-Level) couldn't come close to fitting all the logos on a moderately large screen. Bottom line is unless you take substantial measures to avoid tracking you are going to be tracked by many interested parties, both direct and indirect!
