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?
replyCreators 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
Wording Roblox trying to sell is deceiving.
replyCompare with other platforms. Payout model is as simple as platform takes % or fixed fee, rest is dev to keep. There's no verbiage that says dev share is 67% but you they actually get paid less.
What exactly goes behind the platform is platform's business, not the user. If developers are getting paid out $0.25 per dollar spent, that's the developers profit and rest is spent running the platform which is Roblox's concern.
