Let me get this straight:
It Sony's fault for putting a lock on their hardware to protect illegally copied software from running, and it was this action that FORCED the hackers to break that lock, plus its Sony's fault for making the PS3 too cheap and for not selling software at the price buyers want to pay, and its Sony's fault that people want their software for free?
"Fault" may be too strong a word, but there was a market demand for powerful, open hardware that they weren't meeting. If they can't find a way to turn a profit on hardware alone (like other electronics manufacturers, where the customer's financial relationship with them begins and ends with the hardware purchase), then they've been out-competed. Tough, but that's how it works.
So
1. you have doors with locks in your house, or your businesses has doors with locks to the premises, and when a thief breaks in its your fault, because you fitted locks?
If you didn't buy insurance or have a backup plan for such a contingency, then I'd say yes.
2. I see a fridge I want to buy in a retail shop. i walk in and want it for less. The seller says no. I drive a truck through the stores front door, take the fridge and leave the sum of money I wanted to pay for it, and this is OK, because its the retailers fault for not selling the fridge at the price I wanted to pay for it. Afteral its just the market "self-correcting". Sure, try that in front of a Court.
In this metaphor, is the fridge the hardware or the software? If it's the software, you may have a point, but software piracy doesn't result in collateral damage to sellers, just a denial of sales.
But I'm thinking in terms of hardware. If I buy the fridge and reconfigure it to do something else, for my own use, the seller can't come into my house and undo what I've done to it. In exchange for my modifications, though, I do think it's fair that I waive any claim to a warranty.
I've heard a lot of cocamamy justifications for piracy but this takes the cake: its the IP owners fault.
My main point is that piracy is not the only outcome of this security failure. No question that it's not a good one, but it was a predictable one, and Sony failed to plan for it. They had no proverbial insurance behind their single layer of locks. But if you look at piracy as the ultimate form of competition, they might have better luck approaching it as a sales or access problem. Abusing the purchasers of their hardware isn't the kind of strategy that lends itself to a sustainable business.
