Opera is filing an antitrust complaint against Microsoft in Brazil, alleging it creates an unfair environment for alternate browsers to compete with Edge. The Norway-based company claims Microsoft’s deals to make Edge the exclusive pre-installed browser on Windows machines creates an unfair environment for alternate browsers to compete. Opera also argued that Microsoft uses design tactics and dark patterns to further discourage people from downloading and using rival products. It is asking Brazil’s Administrative Council for Economic Defense (CADE) to pursue remedies against Microsoft.
