This is a most excellent place for technology news and articles.
Older chip doesn't have a 3.0 controller. While disappointing, not really an artificial limit
(Android fan btw)
The cost difference to a 3.2 controller is trivial. It's an arbitrary limitation to differentiate it from the Pro model. They are capitalising on the work done by USB-IF to improve the spec in a way no other member would dream of
Edit: Thanks for telling me about how a $1000+ flagship phone shipping with industry subpar connectivity is OK because they used the SoC from last gen. Truly a revelation.
Not just that, lightning was a similar speed to usb2. It's in their interest to make the pro look like an upgrade rather than highlight just how bad the lightning was really for the consumer
Lightning WAS usb2. Like, USB 2.0 signalling was present on some of the pins on the Lightning port. Since USB 2.0 only needed two data wires that was easy to do.
