alt Hacker News> 67% given to developers per in-experience dollar spent
This is misleading because for every dollar spent, $0.67 is not what developers get paid. The link (https://create.roblox.com/docs/monetize-experiences) you referenced clearly says 25% is the "Developer share".
The cost to run the platform is the platform's cost."Platform hosting & support" and "App stores & payment processing fees" should not be considered as developer operational cost
Roblox games are all multiplayer - you get a game server running in their POPs and a generous amount of persistent storage and memory. How is that not a developer operational cost?
Creators don't have to pay any hosting - Roblox will serve their content even if a game doesnt monetize their users for free.
The way this economical is thru the redistribution of games that do monetize their users
