I am surprised that this does not exist yet for the online food ordering market. Here in the Netherlands JustEatTakeaway has a market share of around 90% and requires restaurants to give them a 14% provision. Restaurants don’t have much of a choice, if they’re not on there they miss out on a huge part of the market, it’s like they don’t exist. Why don’t restaurants unite and develop a FOSS protocol that let’s them federate, so the consumer has a central place to browse the food delivery market, but that makes the providers independant because they can run their own instance if they please. Have these types of ideas been pitched to branche organizations? Restaurants have a clear interest to develop this to free themselves from the platforms with a monopolistic venture-capitol-driven strategy.
