So more Instacart and no more DoorDash for me. Simply uninstalling the app won't cause change, so I contacted both Instacart and DoorDash and asked them to delete my account and all PII and when asked, explained why.
There are plenty of alternatives to both and I suspect we'll pretty quickly figure out which ones are the creepy assholes and which differentiate themselves by being decent human beings. For that matter, it's worth looking at which investors have supported this kind of attitude, as I'm sure this was discussed in board meetings.
