1) The iPhone is the biggest selling single phone on the market, hell they've a 1/3 of the whole market with one device
2) The iPod is the biggest selling digital music player by a mile
3) iTunes is one of the easiest to use ways of managing your digital music collection
So will the vast majority of people give any sort of hoot about DRM when all they can see is their ability to share the music between their PCs and their digital music player? No they will not.
All this will do is demonstrate how pointless the actual demonstration is, thus meaning that Apple will be less likely to be concerned.
For most people the question isn't DRM-free its "playable on my iPod".
