Putting aside the whole "punishing the victim" argument, the problem is that it's excruciatingly hard to draw a line between "being careless" and "you did everything right but it still wasn't enough", and thus it's really hard to punish someone for cybersecurity mistakes. I work in cybersec consulting, and it's certainly true that a large number of companies are simply not investing enough money/time/effort into cybersecurity protections, and are thus doing a disservice to their customers. However, there are also plenty of companies that spend hundreds of millions of dollars, with massive cybersec departments devoted to protecting from breaches like this, doing pretty much everything they possibly can right, and they will still be hacked. Cybersecurity is incredibly difficult, incredibly expensive, and takes a really long time. And even if you get 99.999999% of your company completely impervious to attackers, it only takes that 0.0000001% of exposure to sink your ship. Cybersec is also constantly evolving, so it's nearly impossible to keep up with the latest attack vectors, etc. Take the Target breach, for example: Target has a massive effort focused on cybersecurity. They actually have a cybersec research lab that some law enforcement agencies go to for help with cybersec issues. But the attack that hit them took them totally by surprise simply because it was a type of attack that hadn't really been considered, and thus was very very low on the radar (if there at all) when it came to protecting against it. Now, companies in the US actually are held accountable (to an extent). Data breaches that result in HIPAA violations, for example, usually result in massive fines for companies. Violations of PCI-DSS will land you in hot water with the major payment card companies. Some states also have cybersec regulations that result in fines if you're found to be in violation of them during an audit. The problem, again, is that cybersec is constantly evolving and these regulations are years behind. The HIPAA cybersec requirements are actually pretty laughable, partly because of all the reasons listed above.
