A group of more than 30 states have filed a third antitrust lawsuit against Google, this time focusing on the design of the company's search engine and its tactics to maintain market dominance. The complaint, lodged in the D.C. District Court on Thursday, accuses Google's of anticompetitive behavior with its search engine business, the New York Timesreported. That includes allegedly designing the search engine in a way that pushes out smaller, more specialized rivals. Along with downplaying third-party websites, the state prosecutors also accuse Google of using exclusive deals — like the one with Apple — to prioritize its search engine over rivals like DuckDuckGo.
