I guess because it's a double sided market with exclusivity deals. Consumers aren't going to have multiple service accounts just to get access to delivery. So if you want to reach the most people, you need to make deals with the devil. In this case, DoorDash, Caviar, or GrubHub. It made sense from a brand/marketing cost back when things were normal, but now that it's the primary way to fund your operation, the cost-benefit doesn't make sense anymore, but you're still locked in.
