Whenever we codify something in law - and licenses are a kind of a law use - we're trying to achieve something we mean. So, in many cases in life there are words of the law - or license - and the unspoken intent. I guess you mean that the intent could be different in different cases or differently understood in the same case. Here, with 3D printers, some intended to encourage to make better printers, and some intended to allow the same quality for less, or at least to allow presenting a variety of price-quality offerings to choose from. Sellers already had our money in case we paid those sellers the same money for inferior product. The product of similar quality - even if seller managed to make it cheaper - seems fair game, and with time we'd assume the price to come down. So, we probably have a disagreement on what the intent was or is for the OSHW. For some intents the examples you give are expected.
