Long before Apple was shoehorning the latest from U2 into your iTunes account, it was deleting songs originating from rival services. Tell us if this sounds familiar: You grabbed Lady Gaga's The Fame Monster from Amazon MP3 in 2009, threw it in your iTunes library, went to sync your 160GB iPod classic and got an error message saying you needed to restore the device's factory settings. According to The Wall Street Journal, upon restoring, non-iTunes music would disappear. In the courtroom for the anti-trust case, prosecuting attorney Patrick Coughlin said that Apple directed the software to not tell users about their now-missing songs, too. Cupertino countered by saying that its actions were to thwart any attempts at hacking into iTunes and that users were kept in the dark for a reason. As security director Augustin Farrugia testified:

"We don't need to give users too much information... We don't want to confuse users."
