“Is this a pyramid scheme?”
Ask away. Whoever takes offence at this question is the one not to trust.
WHIEDA uses an MLM model: the products are distributed by partners, not by ordinary shop shelves. MLM in itself is not the same as a financial pyramid. The test is simple: mentally remove the entire partner model. Is there still a product a person would buy simply because they need it? Here — there is. Essentially it's an ordinary product company, just with a different form of distribution: instead of a shop shelf and TV advertising — a person who uses it themselves and stands behind the recommendation with their own name.
