Great investigation! However, the inventor of tea bags never intended them to be used for brewing tea either[1]: >First appearing commercially around 1904, tea bags were successfully marketed about 1908 by the tea and coffee importer Thomas Sullivan from New York, who shipped his silk tea bags around the world. The loose tea was intended to be removed from the bags by customers, but they found it easier to brew the tea with the tea still enclosed in the porous bags. That is, the "correct" usage of tea bags came from the customers misusing the product a century ago. Who can say that unfolding a ketchup cup doesn't follow the same pattern?
