That's true, but you don't really have to let Google know which sites you visit in order to pull the jQuery library. This extension provides the files from a local cache so that you avoid the requests to a great extent and thus minimize any tracking. If mylittlewebsite.com and yourlittlewebsite.com both use Google CDN for jQuery, Google would know that you visited these two sites. With this extension, there's lesser chances of Google or another CDN getting all instances of the jQuery download requests (unless each site is using a different newer version of jQuery that's not locally cached yet).
