That article is about various devs releasing/waiting for the right time to release iPhone jailbreak hacks.
It is NOT a pissant little "developer" coming out and completely pointlessly saying "I hacked this, but I'm not going to detail it, give any hints, encourage anyone, ever release it, or do anything useful or helpful to the community with it."
Now I'm not saying he has to do everything for the good of the hombrew community, but hell, he didn't even say "I'm going to keep this for myself, release a device, and profit off it."
What is the point of this? Just so that when someone does hack it and release it he can claim to have been so smart that he came up with it ages ago? So that a bunch of people you claim not to care about or respect will hold you in some esteem?
I've followed the PSP/PS3 hacking scene to various degrees ever since I bought my launch unit PS3 and I seem to remember this guy being a recurring pain in the rear.
No one cares about you and your phantom hacks, Mathielublah-whatever. Go die in a hole somewhere.
