This is a weirdly untrue comment. The iPod used FireWire for a couple generations before switching to 30 pin and never changing again throughout the rest of the history of the classic iPod form factor.
And a cable has nothing to do with why people buy or stick with an Apple or Google device. A switch to USB C would be better for everyone and Apple knows it (otherwise why switch the iPad to usb c? Why not put proprietary connectors on macs???)
Also? If Apple switched to USB C when it was invented AFTER Lightning, you’d be complaining even harder about how Apple keeps switching their ports to get you to buy more cables. Better late than never
