Latest iTunes update deletes de-DRMized AAC files.
P.S. I had only read the headline, as I don’t have any AAC files: it seems iTunes flags those songs as non playable, and hence deletes them from the iPod (which kind of makes sense), not from the computer. It’s still stupid, as in “DRM”, but doesn’t quite warrant the “microsoftian” epithet.
I wonder whether the RIAA regularly phones Jobs to complain “
OMG OMG it’s terrible people can unprotect the songs they bought from iTunes (duh) OMG OMG you must do something quick”, or Apple’s software engineers take it upon themselves to collaborate the best way they can (oops, Godwin).
