Sorry didn’t see this thread and posted in mine.
I don’t see it as antagonistic at all and that they were actually more accommodating than I thought they would be by including an adaptor with all iphones that anyone can use their existing headphones in. Personally I love not having wires on my keyboard and mouse and would prefer not to have them on my earphones.
All in all I am not sure how this is a bad thing for anyone - the phone is now thinner and water resistant, people who want to sell more things will have more to sell (new product), people who want to sell or use old 1/8in jack stuff still can, and people who want to justify buying new stuff can. If I was in their shoes I think it’s a great move.
It could have been far worse, they could have put U2’s album on everything.
