The Globe and Mail reports in its Thursday edition that Apple was fined 500 million euros ($786-million) on Wednesday and Meta Platforms 200 million euros ($314-million), as European Union antitrust regulators handed out the first sanctions under landmark legislation aimed at curbing the power of Big Tech. A Reuters dispatch to The Globe says the EU fines could stoke tensions with U.S. President Donald Trump, who has threatened to levy tariffs against countries that penalize U.S. companies. They follow a year-long investigation by the European Commission, the EU executive, into whether the companies comply with the Digital Markets Act (DMA) that seeks to allow smaller rivals into markets dominated by the biggest companies. The fines signal that the EU is sticking to its guns in enforcing the new rules, which were introduced in 2023. That is despite Mr. Trump citing the DMA while vowing in February to "defend American companies and innovators from overseas extortion." Alphabet's Google and Elon Musk's X are also facing potential fines from European regulators. The EU will be encouraged by a U.S. court judgment earlier this month, which found that Google illegally dominates two markets for on-line advertising technology.
