Ok, so tell me this: if they have a setup product with a supplier (they do sell keycaps so they must have) what prevents them to leave the injection moulding machines run... forever? If the demand is so high? These machines are capable of insane output for low cost after they are setup. They simply create demand to keep the prices high. This is a different business strategy, similar to business class airline tickets or exclusive fashion clothes. They only need to sell fraction of the quantity for thousands of percent of markup and they can make more money than a mass manufacturer. This whole system if fed by people on social media overpraising pieces of plastic they waited for years.
