Leverage

“The DRM mandated by the RIAA ended up giving Apple leverage. The industry had a choice - they could either agree to Apple’s terms, or drop DRM so that the iPod could play the music from a competitor. The third possible option - dumping Apple and going with a more cooperative company - wasn’t available because the DRM wouldn’t work with the iPod. In other words, the RIAA’s stubbornness in 2000 came back to haunt them five years later.” Baricom, Slashdot comment
