Like the Indian entrepreneur who took on Proctor & Gamble and build his own DIY machine for making low-cost sanitary napkins. http://www.mamamia.com.au/health-wellbeing/the-man-who-wore-...
I think the article misses one important point. Most of the components these makers use are still being done in factories. And, almost surely, if you want to mass produce those makers' stuff you'd still need to approach a factory.
Unless what they mean is that there won't be a need for mass produced items anymore as soon as a lot of makers around the globe can freely reproduce other makers' designs.
