Bro, you don’t really know anything about USB

The port being USB-C has nothing to do with USB 3.0

The port supporting fast charging has nothing to do with it being USB 3.0

Unless you have transferred data over the wire and seen USB 3 speeds, you can’t claim it to be USB 3 based on circumstances alone.

On the other hand, I can totally imagine that 99% people never transfer any data over the wire anymore. Airdrop is fast and convenient if you have a Mac and other solutions exist if you don’t. You can easily get 10 MBps+ transfer rates over Wi-Fi and that works fine for most people, if they ever need to transfer data over to a PC anyway. So I’m guessing Apple just took what majority would accept and went with it, just like any other company does these days.
