About Wednesday last week, a group of professional hackers successfully brought down online access for every user.
Why?
A man named George Hortz jailbroke a PS3 and tampered with it, to get it to work the way that he wanted it to, and he made a video showing off his jailbroken PS3 (which was removed from youtube).
Sony sued George on counts of illegal copyright acts.
"Anonymous", the hacking group did not agree with the sue of Hortz, so they brought down PSN, claiming that PS3 users shall be allowed to do whatever with their system because they paid for it, because they own it.
Sony is currently working on getting PSN back up.
