I do not want Google to have any more fucking data about me than it already does! "Put this blob of JavaScript on every page of your site so that we can see how users are clicking, scrolling, and browsing around. Think of the children^W spam and abuse!"
I just cannot believe that Google somehow gets away with spinning this as some sort of "guardian of the Internet" thing when it is a transparent attempt to a) make adblocking more difficult and b) force people to accept being tracked by Google or get blacklisted from the web.
Getting banned from sites or treated as a subhuman because you don't want Big Brother to follow your actions around should not be something that we're okay with. It just shouldn't be.
