We run a DTC automotive retail website that has both white-label products and vendor products and have product development and manufacturing capability in house. We also sell through multiple channels like wholesale customers, marketplaces, (including Amazon when it makes sense), and a 2 retail stores. Are you saying that we need to dramatically change our business model and can only either be a manufacturer or sell other peoples products because this model is unethical?
