I suppose people don't truly understand the brevity of what Sony is doing.
-George Hotz is fighting an 8 count (last I checked) lawsuit.
-The court ordered he turn his HDD over to a third party for inspection for the files used to hack the PS3 and any passwords that may have been used in an attempt to encrypt those files
-Issued subpoena's to his Webhost, Google, YouTube, Twitter for any and all information relating to VISITORS to his site, those who watched or commented on his YouTube videos displaying the JailBreak, etc, going back as far as January 2009.
-Suing fail0verflow team
-Had German Police raid the home Graf and take his computers and all articles related to PS3 hacking...
And you wonder why Mathieulh won't release the exploit? Anyone who downloaded George Hotz jailbreak could be implicated in the lawsuit (that is partly Sony's attempt...).
