If the exploit wasn't put there intentionally, then we're talking about a bug in the software. Do you really want liability for software bugs? The consequences of that would be substantial. Imagine if Apache or PHP were liable for their bugs used on websites across the internet. The projects would shutdown immediately.. no one could fund the potential liability.
> Do you really want liability for software bugs? For free software? No. No payment, no obligation. For paid products? Yes. If you are selling a device, you should be liable for it, just like a car manufacturer would have liability if the brakes failed because they were improperly installed.
This is a tough problem. We want to punish negligence, not destroy lives because of honest mistakes.
