How're they gonna do that to an offline system like the PS2 or NES? Why should I simply just give up the rights I had on those systems because Sony and Microsoft want more money?
Modern disks are not the same as PS2 and NES disks. The difference between owning something and not owning it is not whether it's on a dedicated physical medium. The PS2 disks are irrelevant to Sony's decision to discontinue disks for future consoles.
Disks with games you own have already been discontinued. Arguing about the format (disk vs downloads) is a distraction.
