Google's parent company Alphabet Inc. must lift restrictions to allow developers to build marketplaces that compete with its Google Play Store, a US judge has ruled, upending Google's dominance of the lucrative Android app store. A federal judge in San Francisco ruled in favour of Epic Games Inc. on Monday in its long-running antitrust lawsuit against Google's app store. Google said it will appeal the decision in the Epic Games antitrust case; it will ask the court to suspend the injunction of the October 7 ruling.
