USB 3 notoriously emits noise in the 2.4ghz radio spectrum, requiring extra precautions and development cost in order to reduce the effect. This is often why 2.4ghz mouse and keyboards specifically require USB 2.0 connections. I’m not saying that’s why Apple did it, but it isn’t a solved problem in the least and USB isn’t just a no-thought upgrade.
