If I ask my User Agent to load a particular news article (for example), I am not intending to ask for a myriad companies to start monitoring my reading habits, social interactions, shopping, or anything else.

When I buy and read a newspaper, I don't expect the publisher to start following me everywhere and keeping a log of my life. When I read an article online, I shouldn't have to think about that either. But sites have so flagrantly abused the ability to deliver more than just the content I've deliberately requested, in order to track (and monetize) user behavior everywhere, that it's entirely appropriate for my User Agent to take steps to defend me.

I don't mind a site delivering some ads alongside the content I've asked for, just like I accept some ads in a printed magazine. But I don't expect my magazine to come with an embedded tracking device that will stick to me like a burr, even long after I've read the content and recycled the pages.
