CMA probes Microsoft business software over browser choice

The UK Competition and Markets Authority (CMA) has opened the floor for comments regarding Microsoft’s business software ecosystem, drawing formal responses from various industry stakeholders, including the Browser Choice Alliance (BCA). This inquiry is particularly focused on Microsoft’s influence in the realm of business software, with an emphasis on the role of web browsers as a pivotal element in this landscape.

Browser focus

The BCA, a coalition advocating for browser choice, has articulated its concerns in a recent submission. It asserts that Microsoft leverages its dominance in operating systems and productivity software to direct users toward its own browser, thereby stifling competition. “The BCA believes that this investigation is an important first step towards ensuring free and fair competition within Microsoft’s business software ecosystem, including between browsers, which are the key gateway for PC users to access the internet and web-based services,” the Alliance stated.

Moreover, the BCA contends that Microsoft’s practices extend beyond mere browser downloads. They argue that the company’s distribution strategies and design decisions within its software environment significantly influence user adoption of various services, including emerging AI tools. “Microsoft leverages [its] market power to hinder merit-based competition, user choice and innovation in the UK,” the Alliance claimed, emphasizing that the company often resorts to exclusive distribution channels and anti-competitive steering practices rather than competing on innovation.

Windows shift

The submission also highlights the transition from Windows 10 to Windows 11 as a critical factor in this discussion. The BCA points out that as organizations upgrade to the latest operating system, Microsoft has yet another opportunity to dictate defaults and sway browser choices in professional settings. “The CMA is right to focus on Windows 11 as Microsoft’s main operating system in the UK business market,” the Alliance noted, indicating that changes in operating system versions can significantly impact how users encounter browser choice screens and prompts.

AI implications

Linking browser competition to the broader landscape of AI tools and productivity services, the BCA argues that browsers have evolved into essential gateways for accessing workplace software and AI applications. As businesses increasingly adopt generative AI for tasks such as document creation, coding, and research, the significance of PCs—and by extension, browser distribution—grows. “The importance of Windows PCs is only increasing in the age of generative AI,” the Alliance stated, underscoring that these tasks are particularly well-suited for execution on PCs.

Furthermore, the BCA warns that competitive issues in the browser space could spill over into the AI domain if Microsoft employs similar tactics to promote its own services. The Alliance advocates for organizations to have the freedom to select AI tools independently, rather than being constrained by defaults tied to Microsoft’s extensive software ecosystem. “Absent intervention, the BCA is concerned that Microsoft will deploy its tried-and-tested browser dark pattern tactics to similarly distort competition and user choice in the AI space,” they cautioned.

In summary, the BCA asserts that the competition surrounding browsers has far-reaching implications for business users, developers, and the software markets intertwined with browser functionality. “Microsoft’s tactics leverage its dominant Windows OS and M365 productivity software suite to frustrate users’ choice of browsers, thereby damaging the user experience and lowering productivity for millions of businesses in the UK,” the Alliance concluded, emphasizing the detrimental impact on innovative browser developers striving to compete and reach new audiences.
