So in the end, Geohot did give out as much as he could to open the PS3 homebrew scene, while not setting the world completely on fire.
When he asked sony not to blacklist his keys, he informed them that they could easily be blocked, but implied that he could create another set. So he could spoonfeed the scene without completely giving up the recipie. (because if he did that it would be much MUCH more difficult to block. I guess he was hoping sony would let the keys slide, if the whole backup thing didnt go nuts like it did.
In the end, I think he did this as a defense from sony. As what he did will be somewhat recoverable within a couple of firmware updates. By the time we hit march, all games will be in the 3.6plus SDK, and untouchable by current measures.
But I believe it will backfire, in the sense that Sony has a valid point in that if he isnt "blocked" from contributing to the scene, he can continually disrupt and cause damage to sony. Whereas if he is blocked, it may end here, as other mainstream "hackers" arent going to waste thier time on something that has been done.
Either way, i'm not so sure that Geohot will go any further in releasing stuff. If he wins the case, he has contributed by setting a precedent for the industry. (Same if he loses) But I doubt he will put his future (he is a young guy with a bright future... bright wealthy future) on the line again, as he has already done it. Unconditionally, and undisputedly done it.
The PS3 is hacked, the tools are there now to put linux on the box. Future motivation has dwindled.
Lets see what happens in the upcommig months, if someone else will jump on the grenade.
