Why can't it be made illegal? And from the article, a very succinct explanation as to why browsers will never be fingerprint-resilient:

> Chromium (Chrome) is built by Google, an advertisement company which tracks its users for showing relevant ads. So naturally it doesn’t have any inbuilt protection against fingerprinting.

Even if they make it illegal, it won't stop bad actors especially from foreign countries to abuse stuff like this. It's better to build better systems that fix this issue instead of relying on government laws.

You could compare it to the concept of security by obscurity which is obviously bad.
