I’m not a cynic, I’m a realist!
If Apple gave a damn about the environmental impact of their business practices, they’d put a headphone jack on their phones and make a user serviceable device. As I see it, they are using an insincere narrative, environmentalism, to gladhand the public about their ongoing phasing out of wires and international standards in favour of proprietary Bluetooth setups and other wireless tech - which has much better margins in the long run. As things are right now, you can still buy a generic set of headphones and hook it up to your iPhone with one of those dreadful dongles; with Bluetooth as the only option, you’ll be locked out of a huge section of the market as every manufacturer will need to pay for a license (about $7 a piece) to make their devices iPhone compatible.
Which will mean more expensive peripherals, more vendor lock-in, less compatibility, and of course more lithium and cobalt for ever more battery-driven devices.
All of which makes the world a worse place to live - unless you’re one of Apple’s shareholders.
