The DRM is not in products that the company own. They sold those products, knowingly, rather than renting them out as a service. Companies should have no right to "protect" lawfully-purchased products against usage by the person who legally bought it.

If they want to sell something and still remain ownership rights, then do what every company in history did before software DRM: rent it out as a service. A car bought, and a car rented, has natural right differences which is being erased by DRM.
