EFF don’t say they know who you are, rather how unique your device appears. This is a problem because if you appear very unique, only if one site knows your identity, everyone can potentially know it.

I understand that. An iPhone should should not appear as unique.

According to Apple's marketing. Yet here we are.

No, this is according to the report that EFF generates. Have you tried looking at it? What on that list lets you identify the device?

And yet... It does.

Buy 2 supposedly identical iphones. Take both to the site. Compare their information.

When you generate a report they tell you which bits of your device were unique. For an iPhone running the latest iOS there is nothing in that list that leaks a significant number of bits.

That's my point. Do it on 2 iphones and compare the information. You'll have your answer then.

If you're confident they're wrong then please spell it out for us. What bits do they claim are unique, and why are they wrong?

My point is they don’t claim any of the bits are unique (all of the individual things are very common) and still someone end up at an answer that is “unique”.
