Antitrust regulators in Europe have fined Facebook €110 ($122M) for misleading them over its acquisition of the secure messaging service WhatsApp.

The European Commission said that the fine would have been more than twice as high but for Facebook’s acknowledgement of wrong-doing and cooperation with the investigation …

Reuters reports that Facebook had claimed it had no way to automatically link WhatsApp accounts with those on its own platform, but this wasn’t true. Not only did it later do just that, but Facebook knew at the time of the acquisition that it could do so.

Facebook said that the statement it made was a mistake rather than a deliberate intention to deceive, and that the EC would have allowed the merger to go ahead with or without the information. The EC confirmed the latter claim.

Facebook remains under investigation in Germany, Italy and the UK for collecting data from WhatsApp in apparent breach of data protection laws.
