While that feeling is present, I think there's an undercurrent you're missing. NYC has a lot of bicycle infrastructure that is designed and managed for use at bicycle speeds, and under the physicals constraints bicycles face. The style of electric bicycle favored by delivery people (and many others) is significantly heavier, faster, and quieter than an unpowered bicycle, so it's easy to see it as an abuse of the infrastructure. There's also an element of classism and in-group/out-group bitterness involved. The people most commonly using these bikes for deliveries are predominantly lower-class immigrants, under heavy pressure to go quickly, and are generally not involved with the (wealthier) "bike culture". There's also a comradery of effort that goes along with riding a bike, the sense that the other people on bikes are putting in the same effort as you. It's granfalloonery at its finest, but I don't think it's fair to attribute this to luddism.
