“As always” is a lie. Moving the tip prompt to after checkout is far more consequential than they’re admitting.
Previously, the way it worked was that you could tip $0 and they would compensate by steadily increasing their offer for the job until a dasher accepted it. This essentially meant that pre-checkout “tips” were bonus money for DoorDash, not the workers. It sounds like that scam is finally going away. No wonder they refer to the regulatory changes as “bad policies”. This is coming in other major markets and they know it.
