Then one would need to ask iTunes about this then. Apple owns the rights to the DRM and if one uses iTunes services then you agree to their TOS. That is non-negotiable. If you own the CD music that is different but DRM music from iTunes is there for a reason. If one doesn't like iTunes DRM rules then complain to Apple iTunes support.
I myself don't like DRM music but it is here to say whether anyone likes it or not. And circumventing the TOS/TOA isn't on your side when you signed the agreement.
