The European Commission has accused Google of breaking European antitrust laws by favoring its own services over rival comparison providers.
The preliminary ruling also states that Google has violated anti-steering rules under the Digital Markets Act by preventing app developers on its Play Store from directing customers to other distribution channels.
Google can challenge the charges and make compliance changes, but the EU can fine companies up to 10% of their global annual revenue for violations, which could be up to $35 billion for Alphabet.
The EU believes that Google's actions negatively impact businesses and innovation opportunities for providers of digital services in the EU.
