What does it matter if there are 1000 variables or 999 variables if it only takes 5 variables to identify people? What point is there to anti-fingerprinting practices if the only way to achieve less than 100% fingerprintability is to stop using the internet entirely? And why, in this sisiphian effort, is the answer to hobble Web APIs, rather than request permissions, as native mobile apps do? Why should there be a functional difference between native mobile apps and web apps? The app stores don't vet submissions, so malicious apps are apparently quite trivial to get into the stores. Users don't really think twice about installing apps. Why do web apps need to be uniquely hobbled in comparison?
