I have JS turned off and still have plenty of other factors that make me unique so it's not just JS. My question is why is the rest of the information available / given, especially the user agent? The other headers mostly make sense. I can see the argument to turn 'do not track' off. But user agent? I've been making websites and apps for almost a quarter century and have never even read of a good use for that outside the tracking industry, let alone seen a good use of it.
