Yes, they are attacking the used game sales. They want to prevent Gamestop from selling the used games for $57 while the new game is $60. The publishers/developers see NO money for used game sales, while the retail store is making ALL of it. Now they (theoretically) force the retailers to sell the used for a reasonable price (20 dollars off) or have the buyer grab a new copy.
Allowing used game sales is one of the rare cases where the law abuses the creators (usually it abuses users). Which respond by abusing their customers with things like DRM and limited activations or lobbying for things like the DMCA. The customers then respond by becoming pirates rather then be abused... and the cycle continues.
Rather then more insane laws to mitigate the abuse of the author with the abuse of the customer, we should just have a sane system in place... that is in this context:
1. No second hand copy of software / games
2. No repurchasing if your disk is scratched, free replacement of any legal copy or online distribution.
There are certainly more aspects. But those two are the ones that are diametrically opposed. Companies are pretending that what they are selling you is both a product and a license, and that the customer is saddled with the responsibilities of both and the benefits of neither. While the authors are given the benefits of both and the responsibility of neither. They should choose one or the other, and license (the one that shouldn't be transferable) should be the only sane approach as the media is worthless. So, no, a scratched disk should not mean a repurchase; because if it does then it is a product, not a license, and you are free to resell a product. (and guess what, EA is of the camp that thinks it does mean a repurchase)
