The three companies, Prestigio, Fly, and Explay, said they weren't allowed to preload Yandex software on their Android phones before selling them to consumers. Yandex's contention is that Google's practices hurt competitors as well as consumers, who are funneled toward Google apps unless they make a conscientious choice to install alternative software. In its lawsuit, Yandex argues that services such as search and e-mail shouldn't be tied to a phone's operating system – they should be allowed to compete on their own merits with services from rival companies.
