If Apple knew they would need to expand this feature past their gear, possible they’d never have implemented.
We may never know what stays unimplemented due to this.
(This is a neutral take - note I do not have a personal opinion formed in this “debate”.)
And this is EXACTLY why they need to open up more core access to their devices. So someone else can innovate.
I'm not seeing an incentive structure for them to change being the only source of good workflows for their users - it's their whole thing "It just works" - regardless of if it's true in practice or not.
It’s just less obvious / measurable that immediate benefits.
And also, short term, isn’t it that other EarPods are getting better, rather than AirPods getting worse?
Medium term, I don’t think that Apple will stop innovating on AirPods just because of the EU market and this one feature not being exclusive to AirPods anymore. But it’s a possibility, I agree.
