First, large scale blocking of cookies undermine people’s privacy by encouraging opaque techniques such as fingerprinting. With fingerprinting, developers have found ways to use tiny bits of information that vary between users, such as what device they have or what fonts they have installed to generate a unique identifier which can then be used to match a user across websites. Unlike cookies, users cannot clear their fingerprint, and therefore cannot control how their information is collected. We think this subverts user choice and is wrong.

"If you don't let us spy on you, we'll have to get more devious about how we do it."

I choose large scale blocking of cookies.
