That’s a bit over the top.
You can still listen to music, in multiple ways, and you only need the adapter if you don’t want to use the earphones they give you when you buy one. No one is forcing anyone to do anything and there is so much choice out there now for consumers they can easily go somewhere else, however, my bet would be on them selling a gabazillion.
While I wouldn’t say it is mindblowing innovation it is still innovative if only incrementally (Not sure if anyone else currently does it?) and I can see the potential for it to benefit far far more people than just Apple, more so than if they just left the jack in it. Universal standards have always changed and were never meant to be eternal, just like the jack.
Again, still surprised.
