Lizard Squad's only motivation is to gain attention and now hold companies to ransom for something they consider of value too them, like vouchers to spend on anything they like just to stop these attacks, but they still carry on, so they have no morals.

It's no hack, a hack is to break through a company's internet security, get into their network, they didn't do that, they just overloaded their servers with more traffic than they could handle and they crashed, not particularly hard to do with web bots, pretty much an automated affair in this day and age.
Sony have a lot more users to cater too, double the number of 8th gen consoles, they have Vita and more PS3 users than Microsoft has with XBox One and 360, which is why Microsoft were up much sooner.
