As I said, my point is just that it's not something I should be obligated to pay for.
But, if you're looking for counterexamples to show it can be done for less than a 15% cut, they're around. Almost every eBay category charges less than 15%, for example. And, as another user pointed out, Epic takes less than 15%. AliExpress charges 5-8% on average. Etsy is I think something like 6.5%.
