They're probably experimenting with their own apps as well as feeling out the market in terms of costing. Plus its "a bandwagon to jump on". They might jump off when they are ready however. Another aspect is their scale. A small business can feel a delivery app taking out a few dollars. A bigger one might be using it as a cost that might only last a few years and seen as "research" to be recovered later. Both can use these strategies however. The smaller businesses converting people to call direct might end up with their own apps and deliveries etc. A lot where I am are actively doing this. UberEats had them but I've noticed a few are setting up their own deliveries now. Others are keeping their options open.
