It used to be that people who bought property became owners. This ownership of private property provided exclusive power over a object, rights to offspring or products produced by it, and governing the use of the object.

DRM eliminates this concept from anything with a computer in it, which in 2015 is most properties of significant worth. The right to govern is retained by he who has the key, which the seller keeps in order to create additional opportunity for revenue. To justify this, the seller argues that this helps reducing the initial cost of the product.

If the property then happens to produces anything of value, say data logs which can be sold, the producer also retains the right to that data by a shrink-wrap license. This is of course insane, as any such schemed used with physical property would be fast put down as fraud. You can't sell a cow, put a 40 page long shrink-wrap license on the gate, and claim thus the milk or offspring are yours. The legal system would not stand for it, especially if it was done large scale with millions of customers.
