Opera has taken a significant step by filing an antitrust complaint against Microsoft in Brazil, asserting that the tech giant fosters an environment that stifles competition for alternative browsers. The Norway-based company contends that Microsoft’s agreements to make Edge the sole pre-installed browser on Windows devices create an uneven playing field, hindering the ability of other browsers to compete effectively.
Allegations of Unfair Practices
In its complaint, Opera highlights that Microsoft employs design strategies and what are often referred to as “dark patterns” to dissuade users from downloading and utilizing rival browsers. This approach, according to Opera, not only limits consumer choice but also undermines the competitive landscape of the browser market.
Aaron McParlan, Opera’s general counsel, expressed the company’s concerns in a recent statement, saying, “Microsoft thwarts browser competition on Windows at every turn. First, browsers like Opera are locked out of important pre-installation opportunities. And then Microsoft frustrates users’ ability to download and use alternative browsers.”
This latest complaint is not the first instance of friction between Opera and Microsoft. The two companies have a history of legal disputes, dating back to 2007 when Opera filed a lawsuit against Microsoft in the European Union, arguing that the bundling of Internet Explorer constituted anticompetitive behavior. More recently, in 2022, Opera sought to have Microsoft designated as a gatekeeper for the Edge browser under the EU’s Digital Markets Act, although this attempt did not yield the desired outcome.
Opera is now urging Brazil’s Administrative Council for Economic Defense (CADE) to take action against Microsoft, seeking remedies that would level the playing field for all browser developers. The outcome of this complaint could have significant implications for the future of browser competition in Brazil and potentially beyond.
