Thats kinda the point being made... He didnt get that far. The machine was a mess, hooked up to alsorts. No way for realistic use at present.
The point is though, it had been done. Sony saw it had been done, and how. So they closed the gap, before it was taken advantage of. Good on them
But what exactly had he done beyond probing memory which he shouldn't have been able to access - he never produced anything 'real' and there's no indication if he would ever have been able to - I still stand by my original post in that they were no more at risk than they were 3 years ago - they just used this as a convenient opportunity to dump a feature the management no longer cared for.
I respect Sony's right to protect their platform - but at the same time I do think that consumers that used OtherOS in addition to other features on the PS3 got a raw deal. I'm disappointed in the way Sony handled it.
