I wasn't denying their existence. I was comparing the process of opening your device, taking out the batteries, finding their proprietary charger or hooking each individual battery up to a USB cable depending on the specific variety of battery, and them putting them back into your device is more annoying than just plugging the device into one of the half dozen USB-C chargers we all have scattered around our homes.

I doubt this would be a dealbreaker for most people, but it's a choice that will provide a consistent small annoyance for users.
