Obvious example, Arduino, which used to stand for Italian Manufacturing and fair wages. Well, that ain't going to be the cheapest thing on Amazon, so now buying a genuine Arduino is both more expensive, not the first recommendation if you search for "Arduino," and a guessing game if you are going to get a counterfeit. Almost everything recommended is ELEGOO, which in my experience is functional but I have had problems in the past with their bootloaders, which I cannot imagine how intimidating that would be for a newcomer.
This is an issue especially when the company open-sourcing their work is trying to boost a local, non-Chinese economy. Whether it be Arduino in Italy or Prusa in the Czech Republic; Chinese manufacturing is all-to-happy to take the plans, churn out clones, and not even open-source the code (let alone the hardware) changes they made. And, I actually, agree with Prusa and think we should not let them do that. I don't know how much they should be required to contribute; but right now it is theft from both the designer (Prusa) and the employees that would have been employed if their design hadn't been ripped off. How many people would be employed with good wages and conditions and were not because cheap, low quality, Chinese labor was willing to fill the void?
