For several years now, Big Tech companies have been held responsible for almost every evil of modern society: the spread of fake news, hate speech and terrorist content; the publishing crisis and the threat to Western democracies; product counterfeiting and tax avoidance. Contrasting with the legislative hyperactivity of Australia, UK, and Europe with regard to Big-Tech companies is the relative inactivity of the US, which is however starting to consider significantly reviewing its antitrust rules and several legislative proposals for modernizing competition law. Europe’s path of technological sovereignty seems to translate into targeting US Big Tech companies in order to limit their competitiveness and favor domestic industrial sectors - something that could cause tension with the Biden administration.
