I mean, yes, but a 3.5mm to usb-c adapter is like $10, so that's still not really an excuse.

Most people use wireless headphones these days, and usb-c headphones are getting more common. (I'm hearing impaired, all headphones sound the same to me, but maybe an audiophile will tell me why usbc headphones suck compared to 3.5mm)

When I bought my new pixel I went to the gym that afternoon and immediately realised I couldn't use my headphones because I hadn't been mindful of my missing headphone jack. Worked out in silence, and bought an adapter on the way home for my headphones. Problem solved.

There's tons of quiet things you can do on your phone if you're bored and don't have headphones.

The only people who are allowed to have their phones on full volume plasting noises without headphones are visually impaired people, because otherwise they'd need to put their headphones in just to check what time it is on their phone.

My brand-new Samsung phone has a headphone jack.

I see what you’re saying though, and while that may be true now, it hasn’t always been the case. If sales of the first iPhone model without a headphone jack had hit an all-time low and people kept buying the older models instead, Apple likely would have realized the mistake and brought it back. They did this with their shitty laptop keyboards and removing the HDMI port and card reader too. But instead, people just complained and still bought those devices anyway, signaling to manufacturers that it was okay, and then others followed suit and here we are now.

There's always alternatives for people willing to stick to their principles. My device still has a removable battery as well and so did the one I had before.
