Re: No, everyone didn't copy.
The Lightening > 3.5 mm dongle is included with iPhones, and when tested is found to have very good sound quality compared to many more expensive third party DACs. Replacements aren't very pricey.
If you want the best sound quality on earphones from a phone, you either buy an LG phone with an ESS Sabre DAC - or else you pick a USB C / Lightening DAC of your choosing.
Samsung's fast charging system predates USB C, and therefore USB C Power Delivery. It ups the voltage, not the current, upon handshaking with the phone. At the time, other phone vendors choose another proprietary fast charger method that upped the current. I don't see what this has to do with Apple.
