alt Hacker NewsI don't agree with GP at all, but making hacking illegal indeed gives companies a false sense of security.
Making burglaries illegal is a real way of preventing many burglaries from happening, because it puts people committing them in prison and deters some from doing it in the first place. This only works because the burglar is in the same place as the burglary, and so they can be arrested.
People with little to no computer experience apply the same standard to cybersecurity and treat foreign hackers the same way as burglars. Then they get surprised when the Russians hack them and the FBI does nothing.
You're presenting a false dilemma, there are more options than "all hacking is completely illegal" and "all hacking is a free-for-all".
We're in a thread that starts from the notion that it should not be illegal to "hack a telecom network and take control of it", because "the people running it did not do a good job configuring and securing it." That's essentially the free-for-all position, and defending it by claiming that the opposite extreme is the only other option is a false choice. Nuance and compromise exist, and our world is made of them.
Also, your argument about burglars can be applied to "hackers", too. Police can find and arrest people domestically and beyond. Consequences deter people from all sorts of illegal activity. On the other hand, nation states are not necessarily deterred by laws from kidnapping and killing people inside the territory of other countries. You've probably seen the news.
What's different is the ease of access to digitical, internet-connected systems, and the scale of abuse that affords. That's a reason to think differently about _how_ to shape the rules and laws around "hacking", but not a reason to have no rules or laws at all.
