You can tell Sony on twitter you don't want restrictive DRM and don't want used game fees for PS4.

I read on neogaf that Sony was going to do similar things as Microsoft, but after seeing the shit storm MS got, they may be changing things. They have been quiet when asked if they will do as MS is choosing because they are considering changing things. No guarantees, and it is good if people communicate with Sony on twitter.
