The European Commission fined Facebook 110 million euros for giving misleading information within the merger procedure on acquiring the messaging service WhatsApp in 2014. The case reached a crossroad of competition law, data protection and consumer law. This was the first time the Commission imposed a fine on a company for inaccurate information since the merger regulation rules were established in 2004. Some authors criticized not only the Commission’s decision from 2017 which imposed the fine, but also the decision from 2014 in which the Commission had decided not to oppose the transaction. Some authors oppose tackling data collection issues through competition law, but some authors raise the question: is competition law enough to consider the case when personal data are involved, too? The controversial part of the decision is not about data protection law, but about the value of personal data from the perspective of competition law.
