Yes, but that's unethical enough to condemn, isn't it? I mean, I was personally horrified that the "tip" that DoorDash had been soliciting with that attractively placed button was in fact really a tip to the parent company and not the dasher. I feel defrauded, and would really like that tip money back.
Whether tips or regular wages are better or not is an endless argument, and it doesn't seem like dashers are particularly exploited relative to other gig economy jobs.
But still... that fake "tip" button was designed to exploit my emotional desire to fairly compensate low wage workers to goose DoorDash's revenue numbers, and that sucks.
