The European Union (EU) is a group of countries in Europe that work together to make rules. They are not happy with Apple, a big company that makes phones and computers, because they control the App Store too much. The App Store is where people can find and download apps for their devices. The EU wants Apple to share the App Store with other companies so it's more fair for everyone. Apple has made some changes to follow the rules, but they still have a lot of power over the App Store. Some smaller companies that make apps might not like this and want to create their own app stores. But if they do that, they have to pay Apple some money every year. The EU says they will take strong action if Apple doesn't play fair. Read from source...

- The headline is misleading and exaggerated, as the EU does not actually threaten Apple with strong action, but rather warns them of the possibility if they do not comply with the new guidelines. This creates a sense of conflict and urgency that may not reflect the reality of the situation.
- The article focuses on the negative implications for Apple, while ignoring the potential benefits for developers and consumers, such as increased competition, choice, and transparency in the app market. This gives an unbalanced perspective that favors one party over another.
- The article uses vague terms like "core technology fee" without explaining what it entails or how it is calculated. This makes it difficult for readers to understand the implications of the new guidelines and why they matter.
- The article cites JP Morgan's prediction that Apple's App Store revenue will not be significantly impacted by the changes, but does not provide any evidence or analysis to support this claim. This makes it seem like an unsubstantiated opinion rather than a credible source of information.
- The article mentions Spotify's decision to allow in-app purchases for audiobooks and subscription plans, but does not explain how this relates to the EU guidelines or why it is relevant for the topic at hand. This adds unnecessary detail that distracts from the main point of the article.
