It's not pirates... That's subterfuge , the real motive is to kill the used America industry.
Only 50% of the revenue collected on video games gets some percentage back to the publisher - the other 50% is solely to retailers on the back of used game sales.
Publishers now want a share of that too.
I agree it isn't pirates...the big corporations see somebody else making a couple of $$ (like GameStop) and they are thinking they can get that share of the money too. And frankly, with the Apple Store making money hand over fist, they see the model working, and they are salivating.
It is sad that it is a zero-sum game...if they make the money off of this, second-hand dealers will lose big time.
Though I still doubt they will introduce this... We ad these rumors last gen too.
I think that some of these "leaks" might be the big corporations testing the reaction ahead of time, and if people don't seem too upset about, they may be more likely to move next time.
Sony in the past has had some "innovative" DRM implementations before, and suffered a huge outcry at the time that has made them retreat. But, with their profits down, who is to say that they shouldn't try this (their shareholders probably think they should!).
Regarding my own purchases, I have been weaning myself off of Steam, and buying more and more from GOG. While Steam is relatively painless, I feel like I am giving in to the big corporate interests...which aren't aligned with my interests.
