As long as there have been cellular phones, they have been "fashion accessories". We all joke about the business guy with the giant phone, but that was the "iPhone X" of the 80's.
When I was at <fairly large financial research website company> they had a prototype VR research project that was shown to a few people. Never seemed to gain any traction, and I didn't hear why.
Probably because a large percentage of their customers don't actually care about expansion. I don't know - I don't have access to Apple's sales demographics, but I would be hard-pressed to think the reason was "malice".
If you're writing your first page as a standalone thing though that matches what the posting is looking for, do you think you need to eliminate unrelated things on the remaining pages?
Some ideas I've had luck with: Have one actionable item per email. State a question in the subject. Expect a clear answer (not quite "yes/no" but something definite). Spend a short time (one or two paragraphs describing the question in detail, but don't make it longer than that.
End the email with the question in the subject asked again.
EDIT: If you find that you need to have a conversation, either walk over to their desk or pick up the phone.
