Hackers are anti consumer in the sense that they are anti-barrier and a security risk. You cannot stop them. Microsoft cannot stop them and neither can Sony. Sure, Microsoft has better security, but Microsoft has recently had issues as well as others with Sony in the past. No one is beyond it. Anyone who thinks in the information age that security is iron clad is kind of losing touch with reality.
I've been with Xbox Live since the beginning and I've never been hacked. I've been with PSN since 08' and I've been hacked twice. The last time I was told by sony's customer service that they won't refund my account again. I bought a game digitally to clear out my account and I cancelled my account and haven't went back. The nerve of sony trying to say their crappy service was my fault for getting hacked! Good riddance!
