threats associated with cyberspace, to reinforce their political power over the masses and to cultivate political repression. Also, in a number of countries, religious controls are the prime motivator behind internet censorship, limiting the exposure and spread of contradictory ideas. Deliberately formed notions of compromised national security and threats to stable social development are also invoked by governments in order to impose internet censorship.
Other than this internet censorship is used to prevent theft of intellectual property such as limitations and reforms imposed against illegal download of copyright content or music. A few governments also use censorship in order to oppress minorities, under the umbrella of cultural restrictions. For instance, the unavailability of certain government websites in different languages maybe viewed as the suppression of certain ethnic minorities. Overall, internet censorship measures adopted by different countries are in fact an act designed to reinforce their political strategies for retaining power. China, Iran, Russia and India are some of the worst internet censorship states engaging in heavy censorship strategies.
