This is a loaded topic. I have no issues with the use of technology. There are lots of pen companies that use mass production equipment. It all depends on your goals and the market you are targeting. There will always be the niche/local market for craftsman made pens.
Most pen kits are mass produced using various industrial machines. If i turn a simple walnut body for it, then that pen is (in my mind) 90% machine made. It is basically a pen with a wooden barrel. And as a point of note, I have never called my kit pens "hand made". I always state that i am responsible for the barrel. While not disparaging anyone making kits, turning a simple cylinder is a beginner lathe project. I often recommend a pen as a beginner project to new turners. What takes these pens up the maker scale, is what we do to change the simple barrel into a not so simple work of art. While the "pen" is still not handmade, when the craftsmanship reaches a certain "subjective" point, the pen parts become overshadowed by the work in the barrel. It becomes a beautiful piece of artwork made into a pen.
In my opinion, there is no black and white line that says if you do this its handmade, if you do this its not. The more and more visible parts are removed or replace with handmade pieces, the more handmade it becomes (in my mind). It is important for the artisan to express what the do and don't do in making there works. I have talked to many people that have bought a simple slimline with the belief that the artisan made the entire pen.
There is a lot of skill and knowledge that goes into designing a 3D object before it comes out of the printer, possibly more than goes into turning a simple maple Sierra barrel. While I would never call the pens above "handmade" I would not down play the skill in designing them.
