Similar model that Amazon uses.

You pretty much have to be on their store to sell something, which means you give them access to your sales and customers. Which is a concept that is absolutely wild in any normal healthy competitive landscape.

Then they'll monitor and if you manage to actually be successful, 3 months later there's an Amazon Basics version of your product.

It's so incredible to me how these practices get no push-back. There used to be a time where in the case of Windows, people were wondering if its fair that they ship it with a calculator program. Now you can just use your massive platform and extend in every possible direction, seize secondary markets, nobody seems to care.
