Is Amway a pyramid scheme?

I'm curious to know if Amway truly operates as a pyramid scheme or not. From what I've heard, some people argue that it encourages recruiting more members than selling products, which sounds similar to a pyramid scheme structure. But on the other hand, Amway claims to offer legitimate business opportunities and products. So, could you clarify if Amway is indeed a pyramid scheme or if there's a misunderstanding about its operations?
