Nobody cares, really, except for a percent fringe users of a percent of Google users.
On a more general point, once again Google Search is provided to you for free. If you don't want to use it by their rules, you are entirely free to use Bing or Yahoo. Actually using the service regularly, because it is tailored to your workflow and provides value to you, while complaining that the tailored/value-adding part is driven by an analysis of your behaviour on the servicee... that's very hypocritical.
I don't use Google, I use StartPage. I am plainly stating that I am surprised nobody made an extension to remove the ping= link attribute from all webpages, considering that the only reason it exists is to track user activity.
That is exactly what is hypocritical about your behaviour: Startpage exclusively uses results from Google, which the company pays Google for. So you are using Google regularly while complaining about it.
