We used to have earbuds that don't need to be charged because they had a headphone jack, didn't get lost so easily because they had a cord attached to a headphone jack, never lost the bluetooth connection because they had a headphone jack, and they cost less because they had a headphone jack. https://bsky.app/profile/daisyfm.bsky.social/post/3l3mfjc6sn62k
I think you meant new iPhones* don't have it. There are new models coming out every year with a headphone jack.
You can still get a Sony Xperia 1 VI, or a 5 VI, or a bunch of mid range devices with headphone jack. There are offerings with headphone jack, so if you want one, you can get one.
Now the problem is we love to complain but not put our money where our mouth is. Has the lack of headphone jack made the iPhone sales suffer? No, they've gone up. Does Samsung sell fewer Galaxy's? Nope. Is the Xperia range a massive success because they have a headphone jack? Not by any stretch of imagination...
...because most people don't actually care enough to vote with their wallet instead of yapping away while they buy a jack-less phone anyway.
That's because getting a headphone jack is lower in the list of priorities than, say, having a great camera. If I could get my current phone in a version having a headphone jack, believe me that I would. I just wasn't prepared to compromise my camera quality for it.
