How about the repeat three years ago?
And let's not forget about "OtherOS" four years ago.
Or profiteering from Whitney Houston's extremely convenient death two years ago.
No, Sony's PR problem doesn't come from "one mistake one department made over a decade ago", it comes from their entire corporate ethos, which their latest woes merely exemplify. They pretty much have made it a holiday tradition of shoving their foot up our asses on a yearly basis, and then expecting us to just smile and ask when the next gen of Playstation will come out so we can re-buy our entire game library that doesn't work on their empty promises of backward compatibility.
