To point A, delivery fees have been around for a while and have never gone to the driver. Is there some app or scenario in which the driver doesn't keep the entire tip? Because I'm not aware of any.

To point B, how is this tech-specific? The question was about why someone driving their car to deliver for Domino's is OK but driving their car to deliver for DoorDash is exploitation.

point A, app based food delivery services with "delivery fee" charged to the customer and not passed on to the driver is a new thing.

15 or 20 years ago if you order a pizza from your local pizza place, the price you pay for the pizza is fixed and known, and you tip the driver in cash. there's no extra 3rd charge line item for "delivery" anywhere.

point B, the advent of app based food delivery in the past 8 years happens to coincide with greatly increased cost of operating the car. I was explaining why traditional method of delivery used to be much more economically viable. Two things happening simultaneously, increase in cost of fuel and operating cars and the increased popularity of app based food delivery does not mean correlation equals causation.

tips weren't that good back in the older days. most people only tipped a $1 if anything and thought the delivery fee went to the driver which in a way it did because they usually got paid hourly plus a small fee.
