Roblox pays 26% of its revenue to Apple/Google for payment processing
Imagine if the mall where you rent your store takes 30% of your revenue (plus a negligible fee). Now think of visa and mastercard that you use to charge your customers: imagine them also taking another 30% cut. That's basically what is happing here.Many here pretend that Apple, Google, MS - first layer platform hegemons - and Roblox, unity, Uber etc - second layer platforms - charging 30% is fair because it's result of competitive market dynamics. But there's no true competition between these platforms. Specially when you consider that the longer a user is in a ecosystem, the costlier it is to move away from it.
