If a piece of anti-fingerprinting software hides more information than it reveals, it's a net positive. If it does the opposite, it's actively harmful. There's probably a nice formulation of this in terms of entropy, but I can't quite state it, so hopefully this makes sense.
1. Everybody uses js. If you have it turned off, you are in a very tiny group, and now you’re easier to track. Remember that js is not the only mechanism to fingerprint a user.
2. Much of the web does not work with js turned off.
If a website forces me to use js in order to use it, I will question it, 98% of them is not worth it in my case.
Remember js was invented to add websites dynamism, not to serve for surveillance capitalism. (Okay, Big corporations was involved in creation of js, but that does not constitute every action they take)
On mobile? You’ve either got an Android phone, or iOS device, either way they ping Gmail and whatnot so Google knows your IP to correlate with.
