My understanding is that these don't actually help. Even their own blog suggests that there is a lot of limitations[0]. And they even talk about how TOR just returns 0. But if everyone did that (say FF did that overnight), then wouldn't that help solve the problem?

Or does there need to be a way to force these things to be pixel perfect (data perfect for the other fingerprinting things like battery, mic, etc)?
