>My thoughts exactly. The information they gained is worth orders of magnitude more.
Which information did they gain? The accounts of Whatsapp? If you read the press release, it says that even if the European Commission had known that they could merge the accounts, the decision would have been the same.
"Today's decision has no impact on the Commission's October 2014 decision to authorise the transaction under the EU Merger Regulation. Indeed, the clearance decision was based on a number of elements going beyond automated user matching. The Commission at the time also carried out an 'even if' assessment that assumed user matching as a possibility. The Commission therefore considers that, albeit relevant, the incorrect or misleading information provided by Facebook did not have an impact on the outcome of the clearance decision."
