It's both - i.e. control is means to an end, which is setting up the rules so that we are forced to live on their terms, which mostly boils down to paying them for the stuff they want us to pay.

DRM is fundamentally an attempt to rewrite reality, or at least the computing aspects of it, in ways that are not possible to do with laws of physics in general. An idealized DRM setup establishes a faux reality, a virtual environment running on top of reality, in which bits have extra rules to it - codifying the weaker attempt of what IP regulations are doing to information in general, i.e. establishing a faux legal reality, in which bits carry colour, and with it restrictions and consequences.

The worst part is, the forces that push us to this direction are shielded in plausible deniability and good intentions, as DRM and cybersecurity are, in the limit, the same thing, so the unhindered capitalism control freaks get to hide behind fear of cyber criminals, while secretly using tools of protection against us.
