Tubberware, is also a firm, with actual products.
- The only reason it's not called a ponzi scheme, is exactly that, they have a physical product.
Now, I'm not saying, that it's a bad product. Nor am I saying, that it's impossible to earn money from it.
- But it's still a scheme.
I'm too tired right now, to actually go into more detail. But I can recommend Penn and Teller for at least the base knowledge.

Most everything is a scheme I guess. Even Steemit is a scheme. You do something to produce results and possibly make money. See I could say here that steemit doesn't work and is a scam because here Jeff comes in and makes thousands while I follow him and someone flags my content and I didn't make a cent. But I would never say that. It is just need to learn the system and make it work for me.
