I once tried blocking all Google domains from my hosts file. Every domain they own set to 0.0.0.0. It was fascinating to see how sites break because of this. The most annoying were logins and registrations failing because of recaptcha. And also embedded maps not being displayed, incorrect fonts, and sites just showing a blank white page when failing to render. That being said there was an noticeable boost in speed for most sites.
