The companies have responded to this escalating assault with vigorous defence and aggressive lobbying, but they have also responded to adverse verdicts by making changes to their business models in different geographies. Meta has stopped targeting teenagers with ads based on their app activity, Google has expanded access to the data used by its ad business, and TikTok allows users to choose a non-personalised feed. These may not be enough. Amazon could face restrictions on selling its own products on its platform because of conflicts of interest with third-party sellers, Google could cease to account for 90 per cent of search enquiries, and Apple could end up changing the rules for access to its App Store. All this when, for unrelated reasons, Big Tech’s share prices took a beating in 2022, recovering partially this year, even as four MAMAA companies announced large-scale layoffs. Big Tech’s battles are on more than one front.
