Olá!
I would say that first it would be wise to verify if the software that
the company distributes with their equipement is indeed based on open
source components beyond doubt or proprietary.
After doing this step, there are more details and facts that help to
contact the manufacturers and explain why and where some of the open
source components that are used require (or not) the source code changes
to be released.
I can help with this analysis. Would you be so kind to provide me with a
private copy of the software that was distributed with the machine?
This way I can process the software to confirm (or not) that some of the
components are indeed GPL and how this might impact the product as a whole.
If you wish to talk in Portuguese, just write a personal message.
With kind regards,
Nuno Brito
