Ok it could be counterfeited
I just question the use of the word 'counterfeit' when talking about 3rd party board suppliers. Clearly counterfeit has a legal definition and to the best of my knowledge in context with Arduino boards, it means that they cannot use the trademark name of 'Arduino'. This is a different issue then if a given board manufacture supports the arduino community or not. The Arduino company purposely released all there design documentation for anyone to use, private or commercial, asking only that all parties respect their trademark, not the design or the right to manufacture 'clones'.
I don't in anyway condone or knowingly support any person or commerical party that does not respect and obey the usage of the Arduino trademark, but that does not mean that 3rd party board suppliers are building counterfeit boards unless they are indeed infringing on the trademark from a legal aspect, irrespective if they 'give back' to the community or not.
