Does anyone know what motivates these guys in hacking sony and pbs?
No.
Support of Wikileaks and opposition to intellectual property as I recall.
.. and annoying PSN users.
THat is anomynous, lulzsec iirc is something different.
I don’t like it at all. First off, it is tresspassing on private property. Secondly, The US will track the IP and bomb whoever is at the receiving end.
Sony takes subsidies from the Japanese government. I wouldn’t consider a house bought with mafia extortion money to be private.
The government subsidizes old people. That makes it OK to rob them.
