Didn't I call this one?

from Listening Post - Wired Blogs:

Apple has declined to explain why its new DRM-free music files are watermarked with users' names and e-mail addresses.


Well, duh. DRMless doesn't mean that you're allowed to trade it, folk. And this is essentially all FairPlay had become -- something embedded in the file to identify its owner that anyone savvy enough could yank out. Instead of trying to beat the pirate, Apple and EMI have simply said that they'll keep trivial tabs on them. Most pirates, aka "normal people", will trade the "unprotected" files without running them through some sort of cleaner, making them easier to bust, in theory.

Now what happens when someone spoofs your email and name in a file they trade?
