It's true that the regulators don't really know what to do about this. I can see why its come about because of privacy issues, and somewhat agree something needs to be done based on a recent experience. I use wordpress for a lot of my web dev, including a couple of analytics plugins, one of which is wp.com stats. Recently Automattic started using a 3rd party that adds user tracking code, in addition to what Automattic already do. There was no mention of this in the plugin docs. It's accepted that Automattic are going to run some tracking code when using the plugin, nut sneaking in another tracker is not a good thing to do and most people would not realise how much tracking is being done.
Anyway, tracking is useful and users should know about it, but this does not seem to be the way to solve the problem. Education is probably a better option.
