your tone suggests one's preferences should be dictated by a corporation's interests; it's perfectly reasonable that the 1/8" jack solves problems for the user that the lightning jack does not solve. Even if they don't even include a 1/8" jack on future products, it could still have been preferable from the individual point of view.
Either you replied to the wrong person or you are majorly projecting your own displeasure. They just asked if the other person was planning on sticking with the iPhone in the future or moving to something that still includes the headphone jack. There was no negative tone to be inferred from that post.
