"I’ve literally played arbitrage between Seamless, DoorDash, Postmates, and a restaurant’s own website"
If you bought food on the cheaper platform, and tried to make a profit by selling it for more on another platform, then you would have 'literally played arbitrage'.
It's the same as when you buy an item from an online retailer, that is shipped directly from the manufacturer (e.g. a large ClosetMaid kit). The price at Amazon and Home Depot might be different, even though the same company is supplying and delivering the item to your home.
