There's absolutely nothing about this particular issue that's even really qualifies as a problem. It's no different than anytime Apple changes something without warning and the product a customer previously bought no longer works with the new device. And it hasn't seemed to hurt Apple one bit.
You've got it backwards. There's nothing about having the 3.5mm jack that qualifies as a problem. Almost ALL headphones out today use that interface. There's nothing lacking in the sound fidelity from such a connection and it's already very small. This creates a problem, it doesn't solve one. And I'd say having to remember to carry around a stupid adapter to be able to use my headphones qualifies as creating a problem. A friend wants to listen to something on your phone? Too bad...if you left the adapter at home.
The 30-pin connector change had some uproar, but it was generally mild because Lightning was a better connector in every way, and the change only affected iPhone accessories anyway. If Apple had already used something like Micro USB on the iPhone and then they changed to the lightning after four years, where EVERY connector in the smartphone world was the same, you'd have had MUCH larger pushback on lightning (even though it's superior).
Even with that, though: What's superior about removing the 3.5" jack? Now I need proprietary headphones that only work with my phone (and won't work with a stereo or my computer), I need a y-splitter if I want to use those headphones while charging, etc. Instead of popularizing USB, which was a universal standard, this change would actually turn a universal standard into a proprietary one. Apples recent change to the USB-C connector on the AppleTV and Macbook is fine (though I think having only one on the Macbook is supremely stupid), because it's a universal standard...most USB devices will likely migrate to that over the next several years. that WON'T be the case with Lightning headphones because it's an Apple-only standard: no other non-Apple phone, tablet, computer or stereo will ever have a lightning port.
It's been quite some time since the floppy disk on the Mac, since the hardware keyboard on the phone, since the dvd drive on the laptop, since flash in iOS devices. Yup, I would say it's about time.
That's just part of what makes Apple so amazing in the first place - that they are not afraid to march to their own step and not care 2 hoots about what other people think. I personally would expect nothing less of Apple.
First, you sound like someone who would buy a new iPhone if Apple came out and said "2 inch screens are really where it's at!" Second, there's a big difference between the floppy disk and the 3.5mm headphone jack. The floppy disk was dying. Apple ditched it earlier than most thought was prudent, but people across the computer world had been searching for a replacement for nearly a decade by that point. Zip disks, LS120, etc...it was a dying format due to its small size and it was going away anyway. The 3.5mm jack? It's never been more widespread and used at any point in history right now. Why ditch it? It's not like it's this albatross that people have been trying to get away from for years.
Yes, it's also annoying to pay for a headphone jack I don't need. Had to do it for years. Enough! I'm a customer too! Let them think of my needs for a change.
Not sure if serious. My guess is at least 80% of iPhone owners (and smartphone owners in general) use the headphone jack on a semi-regular basis.
