The European Union warned Apple on Monday that its App Store is breaching its digital competition rules, placing the iPhone maker at risk of billions of dollars in fines.
It is the latest in a years-long battle between Brussels and giant tech firms, covering subjects from data privacy to disinformation.
Brussels has doled out over €10 billion in fines to tech firms for abusing their dominant market positions.
The latest threat for Apple comes three months after the bloc hit the California firm with a €1.8-billion penalty for preventing European users from accessing information about cheaper music streaming services.
Among big tech firms, only Google has faced a bigger single antitrust fine — more than €4 billion in 2018 for using its Android mobile operating system to promote its search engine.
Google has also incurred billion-plus fines for abusing its power in the online shopping and advertising sectors.
The European Commission, the EU’s executive, recommended last year that Google should sell parts of its business and could face a fine of up to 10 per cent of its global revenue if it fails to comply.
Ireland issues the stiffest fines on data privacy as the laws are enforced by local regulators and Dublin hosts the European offices of several big tech firms.
The Irish regulator handed TikTok a €345-million penalty for mishandling children’s data last September just months after it hit Meta with a record fine of €1.2 billion for illegally transferring personal data between Europe and the United States.
Luxembourg had previously held the record for data fines after it slapped Amazon with a €746-million penalty in 2021.
The EU has had little success in getting tech companies to pay more taxes in Europe, where they are accused of funnelling profits into low-tax economies like Ireland and Luxembourg.
In one of the most notorious cases, the European Commission in 2016 ordered Apple to pay Ireland more than a decade in back taxes — €13 billion — after ruling a sweetheart deal with the government was illegal.
But EU judges overturned the decision saying there was no evidence the company had broken the rules, a decision the commission has been trying to reverse ever since.
The commission is also fighting to reverse another court loss, after judges overruled its order for Amazon to repay €250 million in back taxes to Luxembourg.
Web platforms have long faced accusations of failing to combat hate speech, disinformation and piracy.
The EU passed the Digital Services Act last year, which is designed to force companies to tackle these issues or face fines of up to six per cent of their global turnover.
Already the bloc has begun to show how the DSA might be applied, opening probes on Facebook and Instagram for failing to tackle election-related disinformation.
The bloc has also warned Microsoft that the falsehoods generated by its AI search could fall foul of the DSA.
Google and other online platforms have also been accused of making billions from news without sharing the revenue with those who gather it.
To tackle this, the EU created a form of copyright called “neighbouring rights” that allows print media to demand compensation for using their content.
France has been a test case for the rules and after initial resistance Google and Facebook both agreed to pay some French media for articles shown in web searches.
