The blog post cites an article from The Guardian, with the headline "Apple calls for changes to anti-monopoly laws and says it may stop shipping to the EU". In that article, nothing is mentioned about ceasing iPhone sales. It does say: "warning that unless it is amended the company could stop shipping some products and services to the 27-country bloc" and elsewhere: "It did not specify which products could in future be prevented from being distributed in the EU, but said that the Apple Watch, first released a decade ago, might not be released today in the EU"
The actual press release from Apple seems to be https://www.apple.com/newsroom/2025/09/the-digital-markets-a... and if there's anything in there that supports the headline of this HN submission, it's too subtle for me to find. I think this submission is unreasonably sensationalized, with the predictable effect that the comments here are mostly knee-jerk reactions to the (false) headline instead of discussion of the validity or lack thereof of any specific complaints from Apple.
What's news to me is apparently the European Commission is required to conduct a review of the DMA every three years, including collecting feedback from the public (both users and businesses). So Apple's complaints aren't coming out of the blue; they're part of that feedback process.
