While attention is often focused on the responses of Apple, Google, and Meta to the DMA, Microsoft's actions should not be overlooked.
Recent months have revealed Microsoft's concerted efforts to
either intentionally disregard the incoming regulation or expand its market power before the DMA takes full effect.
This disregard for the DMA manifests itself in a variety of areas, but
notably also in how Microsoft operates in the browser market:
Section 2.1 Microsoft has increased the prompts to users that look for an alternative browser
Section 2.2 Microsoft is imposing de facto Edge default exclusivity and is making it harder for Browser providers to create user-friendly browser default settings
Section 2.3 Microsoft increasingly ignores and overrides default browser settings,including in Outlook and Teams
Section 2.4 Microsoft is leveraging its innovative Bing Chat feature by requiring users to use Edge
