The guy gave you a very valid answer. You asked what people do when the Internet goes out, not how they access passwords. No need to be rude

You haven’t provided a single good reason. Why are you fighting this so hard? Samsung isn’t gonna kiss you.

It’s not hard. It’s wasteful and unnecessary. It means you can’t charge your phone and listen to music at the same time. There are no advantages to removing the headphone jack

How is buying a dongle you shouldn’t need better for the planet than a phone manufacturer providing a headphone jack??? The phone already has a DAC in it, they literally only need to include the actual port

almost everyone I see in public transportation use wireless earbuds. Usually I look like the odd one out for wearing wired earphones.

your sample is incredibly biased, you’re taking 1 demographic and assuming everyone acts like that. Go into a recording studio and see how many wireless headphones they use, Go to a concert and see how they are driving their speakers. Just because a lot of consumers use wireless earphones in an environment that doesn’t lend itself to good audio (like public transport), doesn’t mean most people are using it.

it’s not a redundant component at all. USB-C doesn’t carry analogue audio. You need an external DAC to convert that digital signal to analogue to make it usable. You can’t plug your headphones into a USB-C port.
