Music has a different history and context. The music publishers started to use DRM-free music as a competitive wedge between sellers of digital music, mostly as a wedge against Apple. Then Apple decided to also go DRM-free.

Unfortunately music is backsliding because more of the market is moving to DRM-ful streaming services where you rent your music, instead of DRM-less music that you own free and clear.

Additional factors were Napster and the rise of file-sharing services.

While I agree the history and context is different, I don't see a fundamental difference between the two.
