Facebook has just been issued with a hefty €110 million ($122 million) fine by the European Commission, which acts as the European Union’s competition watchdog.

The Commission said Facebook provided misleading information over its $22 billion purchase of WhatsApp in 2014.

At the time of the acquisition, the social media giant claimed that it could not automatically match user accounts on its platform and WhatsApp.

However, two years later, in August 2016, it launched a service that did exactly that — Facebook essentially updated its privacy policy to allow linking between WhatsApp users’ phone numbers and Facebook users’ identities.

The Commission claims that the “technical possibility” of matching user accounts existed back in 2014 and that Facebook staff knew this but decided not to mention it. Why? Possibly because the company knew that competition regulators like the European Commission would kick up a fuss. Generally speaking, the Commission doesn’t like it when one large company rules the roost — be it in terms of market share or user numbers. The organisation is also investigating Google for its search engine dominance.

Margrethe Vestager, the EU’s commissioner in charge of competition policy, said: “Today’s decision sends a clear signal to companies that they must comply with all aspects of EU merger rules, including the obligation to provide correct information.”

“And it imposes a proportionate and deterrent fine on Facebook,” she said. “The Commission must be able to take decisions about mergers’ effects on competition in full knowledge of accurate facts.”

Facebook said in a statement that the errors were not intentional.

“We’ve acted in good faith since our very first interactions with the Commission and we’ve sought to provide information at every turn,” said a Facebook spokesperson, according to a tweet from the BBC’s Dave Lee. “The errors made in our 2014 filings were not intentional and the Commission has confirmed that they did not impact the outcome of the merger review. Today’s announcement brings this matter to a close.”
