Just a passing tinfoil comment... Google has so many fingers in the analytics pie, if you're not being recorded by Adsense or Analytics, then there's always CDN.
No idea if it's all linked up, but it means that using alternative search engines doesn't really matter if you still visit Google-enhanced destinations.
If that's the case then maybe it would be better for society if we all started self hosted these sorts of resources. Longer load times, more bandwidth usage but better privacy for the public.
I definitely understand the benefit. I also understand the very serious drawbacks of not hosting content that you own. Compared to an initial load time that borders on completely negligible, I'd rather guarantee safety of user information and not having downtime coincide with the shared cdn.
