My weird view of the race to the bottom was a couple years back that I was a happy, paying user of Postmates and received within minutes of each other the emails that Postmates was switching to Uber accounts and that my Uber account was being deleted due to inactivity. I took that as a sure sign that Uber's left-hand wasn't talking to its right-hand, made sure to unsubscribe from my Postmates membership, let their system auto-delete my account, and moved to different apps.
