It's just a tool, like any other tool. Any time someone publicizes a tool as for or against any one thing, it's at most more easily used in that respect for the current time or circumstances.

A bow and arrow can be an effective way to feed your family, or a tool or warfare that changed the outcome of many battles. Advances in textiles can be useful for keeping people warm in winter, or advanced armors with metal sewn inside.

It's not even as simple as a tool shifting from one thing to another either. Bows shifted from a hunting tool, to a tool of warfare, until eventually being relegated to sports equipment for the most part in the modern age. Medieval and Japanese swords used to be the heights of military technology, now they're collector curios.

I'm not sure of any technology that can be used purely for "good" or "bad", or even for one thing at all. The world doesn't often follow absolutes, so we shouldn't fall into the trap of believing absolutes when presented to us. At least not without a lot of justification and the requisite caveats.
