Except they haven't been. Not yet.
There is zero reason to think the EU's ruling has any impact on it. Zero. People just love touting it as some "people's success" over the big bad Apple, but there is no truth to it at all.
1. Apple's hardware models are planned minimum 3 years in advance. The iPhone 15 was designed with USB-C long before this was even a topic of discussion in the EU.
2. Apple has steadily embraced USB-C in many other products, including Mac and iPad, when it was appropriate for those products.
3. Switching the connector on one of the widely-used devices in the world with over 1 billion Lightning devices in existence is no small, casual decision. The majority of the iPhone market cares more about the charging cable NOT changing every other year like it used to back in the early cellphone days. For Apple, it was more prudent to wait until USB-C had grown up around iPhone and become so ubiquitous that it would be a welcome change to users, instead of an irritating one.
4. If Apple's chief concern was to be compliant, they could be compliant only on hardware sold in the EU (albeit unlikely) and they certainly could have waited until iPhone 17. Based on release cycles they could have released iPhone 15 and even 16 with Lightning and still been compliant. But of course, it was never about compliance.
5. Last but not least, Apple promised Lightning for 10 years from 2012 to 2022 and kept that promise to the letter.
No one cares what the EU thinks the hole on the bottom of luxury technology products should look like...least of all Apple.
