The free delivery is a meaningless "benefit". I would never have people pick up my food in the first place if I wasn't trying to burn credits to get as much of my AF back as possible. All that does is increase the amount of time between when it leaves the kitchen and when you eat it.

Yep and it's the same with UberEats. Uber used to have all of these promotions for free delivery and used to not have service fees, and I burned my first few Amex Platinum credits on such orders. Then they started charging a 15% "service fee" on top of the delivery fees but thankfully added the option to pick the food up yourself, so I always do that now (which avoids all extra fees entirely). It's better doing that anyway because you can arrive at the restaurant before your order is ready and get it just as it comes out of the kitchen. If you end up using a courier, then not only might that person drop off food somewhere else before he or she drops off your food, but there's generally a delay between when the food is ready and when it gets picked up on top of that.

People who have been strictly part of the Chase ecosystem and haven't played the game with Amex are really going to be disappointed by these changes. It's far more annoying getting value out of services like Doordash and UberEats than out of a liberal $300 travel credit because these services try to nickel and dime you at every step along the way, which further reduces the value of what they're selling.
