Bluetooth is slow and unreliable unless you're using Airpods (due to the W1 chip), which I think is the more subtle move by Apple in this case. I was not a happy camper when I first read about Apple removing the headphone jack, but I won't lie, I'm an Airpod convert. They work flawlessly for me and I haven't traveled with or used normal headphones since I got them (other than a nicer pair of over-the-ears when I'm working on my desktop).
I'm not saying this excuses the removal of the headphone jack, but from a business perspective it does add up.
