Yup. I want all these people who are in favor of Apple to return their macbook chargers as well. I mean you can charge macbooks using any USB-PD charger, no? So why do they need a charger? It's for the environment!
I wouldn't be surprised if Apple within 5 years makes it an add-on. They just need powerful USB-C chargers to become more ubiquitous.
You can see signs today, when you have to pay extra to get a better charger.
