I use DDG, as well, but I think you're missing the point. It's virtually impossible to avoid Google. You visit some sites, and they use scripts or fonts hosted by them, or use their services such as captcha, maps, etc.
If you use Android, virtually all apps rely on Google Play Services, and interestingly you it will autoupdate even when you explicitly tell it not to.
Using google maps to navigate (now even Waze is theirs), people sending links to google docs, google pictures etc.
While some data is stored, no cookies are sent, plus there's heavy caching involved: "The result is that website visitors send very few requests to Google: We only see 1 CSS request per font family, per day, per browser."
All in all, those services (IIRC the JS library CDN is similar) don't seem to be designed to be a tracking data source except for some popularity stats about the data hosted there.
