The US Department of Justice antitrust case against Google alleges an illegal monopoly in search and search advertising in their home and largest market.

The lawsuit targets Google's control of the Android mobile operating system and exclusive revenue share agreement with Apple, which the EU prohibited in 2018, a decision that Google has appealed.

Alongside antitrust enforcement, legislative initiatives in the EU and UK will create an ex ante antitrust framework for relations between “gatekeeper” platforms and their users and customers, which the US Congress has yet to emulate.

ByteDance is rushing to sell a 20% stake in TikTok Global to Oracle and Walmart at an enterprise value of $60 billion. TikTok otherwise faces a ban in the US on 12 November, subject to legal challenges.

The sale hinges on ByteDance obtaining approval from China to export TikTok’s core technologies. China updated its export control rules to include algorithms (and AI), entrenching a tech cold war with the West.

TikTok has confounded regulatory woes in India and the US, and renewed competition from US tech, to post dizzying user growth in every major internet region where it is available, casting off its image as a niche youth product and entering the mainstream.

Press reports suggest that the restrictions on Huawei equipment may morph into a full ban, with new installations stopping soon and existing equipment to be removed by 2029.

The direct ‘tear-out’ and replacement costs for mobile would be very high at up to £2bn, and there would be significant disruption to 5G roll-outs as operators’ focus moves to replacing what they already have as opposed to pushing into new coverage areas.

Previous rules applied to fixed line broadband networks with as much force as mobile; having to replace Huawei broadband kit would almost certainly delay the move to ‘full fibre’, for no good reason even according to the government’s own report.

Apple’s developer conference coincided with a period of unprecedented tension with its developer community, parts of which are chafing under Apple’s rules for the iPhone App Store.

These rules let Apple extract a large portion of the value of the App Store. This revenue is more important than ever to Apple’s growth story, so it has been applying its rules more strictly.

Apple is constrained here by the need to deliver the best product possible to its users, and by the possibility of regulatory intervention.

Despite operating in a challenging market, Sky has continued to increase revenues, with the resilient performance of its direct-to-consumer and content businesses offsetting the disappointing drop in advertising income.

Across FY 2019, EBITDA was up 12.2%; profit growth driven by a significant reduction in “other” costs as large one-off effects disappear and cost-cutting continues.

Extended distribution deals with Netflix and WarnerMedia will protect Sky’s content proposition for the coming future, as would the mooted integration of Disney+.
