If you operated a mall that costs money to enter, then you will put only the stores that give free samples at the front, to attract more customers. In that environment the stores will compete to give bigger and flashier free samples, and at the same time work on ways to monetize the customers. If you had a store that just sold your product upfront you will be pushed far to the back. You don't attract customers to the mall, and everyone else is offering free samples. Google and Apple's incentive to feature and promote free apps created what is a very toxic race to the bottom in their app stores. They put the platform ahead of the product. This is their doing rather than a natural occurrence. Nintendo has been selling game for full price for decades but even it couldn't do it on the app stores, and they had to resort to variations of gambling and f2p.
