Lets not lose track of the fact that both these issues, (Norton and Sony), were well intentioned attempts to protect. The real bad guys are the ones that malliciously try to exploit these things.
I am not condoning what Symantec or Sony did, (and lets face it, there are probably others that simply haven't been caught yet and are furiously trying to remove this stuff), but lets remember, the bad guys are the hackers and the pirates.
If they weren't there, then we wouldn't need to spend a fortune on security software, or pay inflated prices for software/music/video to cover losses due to theft.
Once again, the excessive profiteerig by certain companies is another, equally condemable offence.
