I guess the business model for DoorDash is to 'lock' customers (both receiving and sending side) into their systems. Once ingrained to a point where it is painful to extricate, prices creep up till it is profitable? Sort of like cable TV, satellite radio, Youtube, et al. I remember all were initially introduces as 'no commercials, that is what the monthly fee is for', or 'you will not see commercials in our videos'. Today, none of these media can be watched without advertisements. Step one, present something slightly more convenient, or less costly than status quo. Step two, wait till every frog is comfortably swimming in the pot and abandons original something. Step three, put lid on pot, but keep telling frogs that it is for an improvement. Maybe even get Gov to declare original something was dangerous, think of the children! Step four, turn up heat and start charging big bucks.
