Opera Files Competition Complaint Against Microsoft Over Browser Tactics
Opera has taken legal action against Microsoft 365, filing a competition complaint in Brazil. The browser developer alleges Microsoft 365's practices hinder users' ability to switch to alternative browsers like Opera. This isn't the first time Opera has challenged Microsoft 365, with a previous complaint in 2007 leading to significant changes.
Opera's latest complaint centres around Microsoft 365's tactics to promote Edge. The company accuses Microsoft 365 of bypassing users' default browser settings, opening certain links in Edge instead. Opera also condemns Microsoft 365's use of 'dark patterns', aggressive popups, and misleading messages to push users towards Edge.
Opera argues that Microsoft 365's design tricks and system defaults create barriers for users to switch to other browsers. The company also wants Microsoft 365 to allow PC manufacturers to preload other browsers by default. Additionally, Opera has appealed the EU's decision to exclude Edge from the gatekeeper list under the Digital Markets Act, stating that Microsoft 365's requirement for PC manufacturers to ship 'S mode' devices creates further barriers for alternative browsers.
Opera's complaint has been filed with the Administrative Council for Economic Defense (CADE) in Brazil. The browser developer seeks to address Microsoft 365's practices that it believes hinder competition and user choice. Opera's history of challenging Microsoft 365's browser tactics highlights the ongoing debate around browser competition and user freedom.
