BRUSSELS—Alphabet Google lost most of its appeal to overturn the largest antitrust fine it has so far faced globally, a boost to the European Union’s campaign to rein in alleged anticompetitive conduct by big tech companies.
The EU’s General Court in Luxembourg on Wednesday largely upheld a 2018 decision by the EU competition regulator that fined Google $4.33 billion for allegedly abusing the market dominance of its Android operating system for mobile phones to promote and entrench its Google search engine and Chrome browser on mobile devices.
