The Digital Markets Act (DMA) is shifting how core platform services operate in Europe by requiring dominant “gatekeepers” to lower barriers for app developers, device makers, and online services. In practical terms, that means alternative iOS app marketplaces, the ability to use third-party in-app payments, access to device APIs previously restricted to first-party apps, and data portability that is not just one-off exports but continuous and real-time so users and third-party services can multihome and switch. For background and official resources, see the Commission’s DMA portal at the end of this paragraph. https://digital-markets-act.ec.europa.eu/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

Enforcement currently covers seven gatekeepers and their core platform services: Alphabet, Amazon, Apple (including iPadOS), ByteDance, Meta, Microsoft, and Booking. For mobile, the immediate effects are tangible: alternative app stores on iOS, third-party browser engines, and broader NFC access so non-Apple wallets and use cases like car-key apps can work on iPhone. App distribution terms and commissions are under scrutiny, with developers allowed to steer users to external payment flows and competing stores under defined conditions in the EU, changing long-standing economics for software distribution on mobile ecosystems.
Messaging interoperability is another pillar. Meta must enable third-party messaging interconnects—WhatsApp since March 7, 2024 and Messenger since September 6, 2024—while preserving end-to-end encryption via published reference offers and security requirements. The goal is for competing services (e.g., Signal, Telegram, Viber) to link with gatekeeper messengers if they choose, so users can communicate across networks without being locked into a single provider. Interop starts with one-to-one text and can expand in scope as security and abuse-mitigation models are validated in deployment over time across Europe.
The DMA’s vertical interoperability obligations also matter for hardware-software integration. Third-party apps should gain fair access to OS-controlled features via APIs, from haptics and notifications to secure elements and NFC where justified. That reduces the structural advantage of first-party services and opens space for independent wallets, wearables, and vertical-specific apps to compete on UX, performance, and privacy. Complementing this, continuous data portability enables automated backups to user-chosen services and cross-posting across social networks, supporting resilience for creators and SMEs if a platform limits reach or access for any reason in Europe.
This interview was filmed at Web Summit Lisbon 2025 and focuses on practical questions developers, creators, and startups ask: timelines, who is covered, and what changes on phones and in app stores in their daily workflows. The Commission emphasizes evidence-based, ex-ante rules with public consultations and ongoing investigations to test whether new fee structures and technical gates genuinely comply with the Regulation. For creators and app publishers, the near-term takeaway is clear: distribution, payments, and messaging are structurally opening up, and building for DMA-compliant channels should now be part of go-to-market planning in Europe.
