Apple tore down the walls of its own garden a few YEARS ago, when they started allowing full-blown Sideloading of any ol' iOS App the User wanted.
So we should just ignore the rules of the store (though shall not compete with any of our apps/services)? Or the fact that to develop for their platform, you need to already buy into their platform? Ex: You can use a Linux box to build a Windows, MacOS or Linux app pretty easily, and per all of the rules, however if you attempt to do something like... build a Xamarin app in... Visual Studio on Windows, suddenly you require an MacOS device to do the building. Not for technical reasons, but for legal ones.
when a large percentage of audio equipment was still shipping (and some still does!) with 1/4" jacks?
Stationary maybe, not portable.
Thinking back on just my own purchases... I do not recall ever owning a portable cassette (boombox or Walkman), CD or MP3 player which had a 1/4" jack, only 3.5mm.
Hell, even the original Sony Walkman back in '79 only had a 3.5mm connection.
Because, JUST LIKE APPLE, the headphone manufacturers INCLUDED AN ADAPTER. So, pray tell, how is this ANY different?!?
And over the years I got many of those adapters... even later airplane ones, never used any because mini-stereo, a widely used standard had won out as anyone could implement it. PCs, portables, autos, airplanes, you name it. Can't say the same about Lightning, can we?
And don't bring up the ridiculously-overblown bug-boo about "Charging while listening".
So all of those people who actually have that as a problem are wrong... because *you* are ok with adapters and think the battery has enough capacity for your type of usage? Good for you! Not all of us are so easily sold.
Some of us may use our devices heavily when not in a location we are able to charge, but once we reach our car want to add some juice while listening to audio from the device.
Second, there are about a dozen adapters, some as inexpensive as $10, that allow doing just that.
Yup, none which have the ease of what existed before (ie not having to deal with a dock or some small brick hanging from your device if you happen to pick it up). I continue to be surprised no one has released anything as simple as this one, but for lightning as it gives you the benefits of a single cord, and puts any clutter of the mini-stereo cable away from the handset.
If you have spent $700 on a new phone, one would think that $10 wouldn't be that much of a financial hardship, eh?
Maybe... it's not about the money?
Heck, if you are so quick to dismiss the legit concerns about "charging while listening"... perhaps you should do a better job understanding the concerns?
Personally I usually have a pair of earbuds in my pocket... they work just fine with my cell phone, tablet, laptop, even my gaming controller. If I owned an iPhone 7, I could simply carry that adapter with me all of the time and use it where needed... however that gets into a lot of hassle. Or I could drop $10 per location I usually plug in some audio device (home, work, car, work area in garage, etc)... but then I am participating in a sort of balkanization I have zero willingness to join in on.
Oh, and the reason that Microsoft APPEARS to be moving in a more "Open" direction? THEY ARE SCARED TO DEATH. Period.
You really should look into the Satya kool-aid a bit more, it's not as simple as that.
