Nowadays, virtual social networks have been widely spread all over the world and have become part of the daily lives of citizens. In Iran, virtual social networks have a high penetration rate, and the influence of social networks, which are mainly foreign messengers, led the country's cultural and communication policymakers to compete in this field and to replace native messengers by designing and supporting native messengers and filtering some of the popular foreign messengers. But despite financial and advertising support, the plan to replace native messengers such as Soroush, Bisphon, or Ghap or compete with foreign messengers did not succeed and was not accepted in practice by users. The purpose of this research was to study the reasons for this policy failure and the lack of acceptance by Iranian social media users. Therefore, some Iranian users were interviewed. Their most important reason for not welcoming native messengers was political distrust and fear of misusing information of user by government, and the technical and logistical weakness of these messengers.
