@michel_slm Good resolution! Regarding the free hardware thing, a lot of the important freedoms with software are still the default with common hardware. I.e. You can use the hardware as you wish (commercially or whatever), you are free to study and modify your hardware, and you can sell your hardware on (even modified). The only thing really missing is the right to make copies of the hardware.
This is free hardware: *points at hardware with open source license*
Now, this is open hardware. *Points at normal hardware*
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
