The problem is not the charging. The problem is that a fake charger cable can run an HID attack over the +/- pins before it does a pass through to the power negotiation MCU for charging. A tampered USB C to C cable on a conference room table can compromise people all day long. If the USB C charge ports cut the data pins entirely then great, but I have not seen that be the case on any laptops yet.
