Job's anti-DRM letter was published 8 months before the public beta of Amazon MP3 in September 2007. The first DRM free music from EMI was available on iTunes in May 2007. Google Play Music opened in 2011, two years after iTunes music was fully DRM free in the US.
"Eventually" is a bit harsh, it isn't a given that Amazon MP3 and Google Play Music would be DRM free if it wasn't for Apple pushing for it back at the start of 2007.
It's not good to attribute all that credit to iTunes. Amazon and Google may have been able to negotiate other terms. Because unlike Apple, neither Amazon or Google had a separate MP3 player and thus no incentive to enforce DRM.
Seems that every thread has someone claim that if it wasn't for Apple, X would never exist and I'm frankly tired of it.
