I thought this too for the longest time. Then I heard an anecdote from one of my colleagues that does licensing: The music licensing industry heads (RIAA/MPAA/ASCAP/etc) are tiny fish monetarily, but they own everything and control it. If the RIAA doesn't like you, they can make you go away. The issue is that if anyone wants to fight them on Antitrust grounds, this turns the big light of Antitrust litigation around on those big fish that depend on Very Carefully not being in the spotlight. Putting it differently: if Google tried to do anything, their counter would be calling the licensing bodies anticompetitive, which puts Google in the crosshairs next.
