Let me lead everyone on a bit of a rabbit trail here, because this is very hypothetical. Still, I think it makes sense. Now, consider for a moment that the advent of and rapidly increasing accessibility and affordability of 3D printing may put common goods manufacturing into the hands of the consumer... and takes it away from the gigantic sweat-shop operating acmetm cartel. For Acme TM, that's scary as hell. Their business model goes away and, in spite of the fact that their once employees are now able to better take care of themselves via access to cyclical 3D reprinting technologies, the CEOs no longer have 1% style leverage and wealth. Said CEOs may want to find some way to turn the public AGAINST 3D printing, thus, before this paradigm shifts. Now consider, for a moment, than scared-irrational (or hobbyists) are printing 'illegal' triggers for guns, circumventing a community's ability to track and deal with said deadly weaponry. Prior to now, big-business interests have been mostly pro-gun because people, in general, are kinda pro-gun... but if you can use 3D printed triggers as a wedge issue to scare people away from 3D printing as a practice (thus ensuring your future as a law-leveraged manufacturing monopoly), do you really think they won't try? To be blunt, I personally am anti gun. I don't like them. I think they cause 10x as many problems as they solve, etc. But I also detect the possibility that a world in which people can see to their own common goods needs, underlying causes of violence will diminish and thus the desire for guns (and violence et al) will likewise go down. Sorry, I'm novelizing... the point is, I suspect that we will see (like this article, like some media lately) will overinflate their interest in gun triggers to silently try to rob the world of 3D printing as an individually available ability.
