If they are that concerned with resell rights why aren't they going after iTunes, Amazon Video/MP3, Google Play, and countless others for the same reasons. Seems a bit strange. I am pretty sure you can't transfer your songs to another person or resell your apps on your phone/tablet.
I would have thought iTunes/appstore would have made a better example. You know how large the marketshare being that they are on about 50% of the phones and tablets and defacto monopoly for digital music.
