Listening Post reports that Apple are watermarking tracks with the purchaser’s email address. Not really surprising that, at least to me. I’ve been doing some thinking about this area for the last while
What I find a bit objectionable is that Apple apparently didn’t bother to tell its customers that it was doing this. I can’t see why they wouldn’t.
I think it’s a good idea though. It makes tracks usable and sharable but puts some sort of limit on the extent to which they will be shared.
You could still scrub the watermark off the tracks without too much hassle, but why would the average consumer bother?
