I agree, but it all comes down to what they are sending. Sending "some anonymous device (assuming they cab truly keep things anonymous, a non-trivia, task!) is around here" is probably OK. Sending "device ae4f3297ffd is around here" is most likely not ok at all.
I agree, they are sending more info than they need to, in the same way Apple didn't need to store these data for so long or back them up on a computer. In both cases I don't think there is malice, but it's good people actually check what is going on and force vendors to take privacy seriously.
