I do use Instacart and, as described above, tip outrageously. Also, while it is possible that they are lying in their teeth, Instacart sent out an email a week or two ago proudly, if tardily, proclaiming that they were providing (Free of charge!) "shopping kits" to their shoppers, with gloves, masks, and hand sanitizer. So it was very late, but if this is true they are now providing a modicum of protection.
