SpyTunes
Andrew McAfee (via Jeff Johnson):
I’ve been doing some poking around, and have found that it’s pretty straightforward for one person (let’s call him George Smiley, after John Le Carré’s master spy) to find out what music, video, and apps someone else (like me) has purchased or had gifted to them on iTunes.
Probably not a huge deal for most people, but it would be nice for Apple to respect the user’s privacy by default. We’ll see what happens when iBooks supports gifting. The Kindle solution seems reasonable.
