I believe the real purpose of progressively more strict DRM is to get us closer and closer to every publisher's utopia of eliminating the sales of used games, while keeping games at $/€ 50 or above.
They know digital distribution is going to take over, and they want people to get as used as possible to not being able to gain value by reselling games, while still paying the same price as now.
It's not for pirates. It's an attempt at controlling our views of what we buy.
There, I said it.
