> Sony's announcement follows Rockstar's announcement that Grand Theft Auto 6 will come with a download code in a box rather than a physical disc. It's a move that most notably stamps out second-hand reselling of a game.

This is the big point for me. If one buys a digital PlayStation game there's virtually no easy way to transfer it to another owner or sell it like one could do in past console generations. There will always be modding and ways to play game dumps, but it limits that level of "ownership" to those technically inclined to make it work.
