does no one see a problem. when i buy something it is my property and that means the company already has the money that i spent on the good. it is therefore my choice on what i can do with it. if i sell it to gamestop it's the same thing as if i'm selling it to a friend or a stranger who wants to buy the game, where as gamestop acts as an agent to make trades and exchanges easier.
the problem is that there is no problem with gamestop selling used games because those used games are from people who bought them new, which means the game companies already have their share, and the buyer of that game has the option to sell it since it's his property now. so why should the game company get double dip on profits from used games if they already got shares of the sales from the first purchase?
truly the guy speaks the truth, the use of drm is not to prevent piracy but ownership. this means that the game companies aren't trying to sell you a product to own but are trying to sell you a rental of the game.
