Meh. This attack is going after the easiest of targets. If a medical device or something critical is victim to this, they should cease to exist. I find it easy to believe that this attack protects far more people in the long run than it will ever hurt right now, and I'm willing to take that side of the moral dilemma.

It would be nice if we could live in a world where we all trust each other, and maybe with physical things this is attainable. But the IoT is a worldwide attack surface. It's open to nefarious actors ranging from junkies with stolen laptops, all the way to state-sponsored hacking organizations with billion dollar budgets. Trust and goodwill aren't options anymore.
