DRM has nothing to with policing.

If the DRM kicks in, the product might stop working.

If you get "policed", you might end up in jail by force.

Policing doesn't need to imply jail, it can mean any policy enforcement, such as: the enforcement of regulations or an agreement.

DRM is without a question a policing method, one that's preemptive and overreaching by its definition.
