This is quite an interesting proposition. And with regards to the concept of incentivization, it makes sense to some degree.
But morally this just feels skewed.
Why exactly would the people putting the items we make be receiving a larger cut of sales compared to us UGC creators? We take the time to create, refine, and upload items for users to enjoy, yet are given an even smaller cut than those who don’t even give a direct aid in such a process. It’s infuriating.
