If specific publishers put up restrictions how is it Sony's fault? This is exactly how it is on PS3. Nothing has changed on this matter between PS3 and PS4 and Edge runs this as a news article? Terrible sensationalist headline that creates confusion for people when Sony came out and said 100% they will not have forced DRM on their games and that only the publishers can limit their own online games in these ways.
While Sony didn't lied, if some publishers do come on with DRM for the PS4, then who do you think people are going to blame? Sony.
It's true that a publishers decision won't be Sony's fault, but I bet that if EA comes out with something like "offline passes", then people will point the finger to Sony and say "They lied to me!". Hopefully people are smarter than that, but most of the cases they aren't.
