So what? They have shown no indication that they will become less evil. Why would you buy computer equipment from a company willing to hack its customers?
Lots of large companies do lots of suspect things and you never hear about it.
I'll know about it if I'm one of their victims. And, so it's "well, everybody else shoplifts and teases nerds, why shouldn't I?" Just because someone else is being evil gives you no right to be evil as well.
You might think its karma for Sony getting hacked but what about all the innocent people who get hurt too?
I don't believe in karma, and I was one of the innocent people Sony's hacking hurt. If Sony's stockholders get hurt, GOOD. Owning Sony stock is evil. Their employees? What is a company, but its employees? Would you work for the Cosa Nostra just because they were hiring? Then why would you take a position with them?
Hacking Sony harms no innocents. If you work for them, you're part of the problem. If you own stock you're the biggest part of the problem.
Why are defending evil? Are you a Sony employee?
