As the source article covers, some manufacturers routinely ensure this kind of closer connection through contractual promises from authorized retailers. (Obviously any individual person who buys a product can still resell it, but for things like clothes consumers widely understand this to be a separate "second-hand market".) Amazon invests a lot of effort themselves in the consumer experience, they understand very well that stuff isn't just stuff and it matters how you sell it.
