On the other hand, mandates of this sort can stifle innovation
Urgh only an American website would say this. It's not innovation to force users to use a cable that's maximum speed is still USB2.
All people want to do is charge their device with the same cable. Sure it would be nice if all devices with USB-C worked the same but it's unnecessary because a phone isn't a laptop isn't a digital camera.
This is a win for everyone. Sure I get government control on big business, Americans just dislike as a rule but when its common sense.
No one likes iPhones and Android phones don't use the same chargers. No one likes having tonnes of messaging apps to use.
Where is the American government forcing Big Tech to play nice? It's the EU doing the leg work.
