Who gives a rats ass about benefiting publishers? I'm not a publisher. I'm a consumer. I care about what benefits consumers the most and having the ability to sell/buy second hand games does exactly that.
...The publishers do. You know, the ones who actually make these decisions. They don't care what benefits consumers if it doesn't benefit them. Giving consumers the ability to throw aways sales does not benefit them, which is why there's an obvious push to get rid of physical. This is a business, not a charity.
Well, this is new.
