Wasn't Doordash one of the companies that was lowering payments if tips were added? Eg, if they were going to pay $10 for a delivery, and someone left a $2 tip, they would reduce what they paid to $8. The driver gets $10, rather than the $12 you'd imagine. I have a hard time reading anything charitably about the company. If you exploit your workers, I don't care how scrappy and clever you were in bootstrapping.
It's one of those companies, which give tech a bad name.
