Most of the places in the world has free access to the Internet. There’s an immense portion of the world that is still restricted to the access the content that is censored.
Social media isn’t just a place for pictures of cats and dogs. Many people used it as a place to unite and create uprisings. So in some places what government does it they take actions to censor the internet content by blocking or deleting or just by making it inaccessible.
Countries including Azerbaijan, Belize, China, Iran, Kuwait, Morocco, Oman, Paraguay, Saudi Arabia and United Arab Emirates don’t allow voice calls(VoIP) via Skype, Whatsapp Or Viber. Also there may be restrictions on messaging too. For some countries voice calls works via WiFi but not with mobile networks. The reason for blocking VoIP services is because the government companies don’t want to lose the money which they earn from mobile services. Everyone knows that VoIP is way more cheaper than the international calls. Wherein Skype, Whatsapp, Viber & others are free of cost.
In North Korea, China & Iran the reasons for censorship are social networking platforms were used to coordinate anti-govt protests and to prevent non-govt approved communications. North Korea is way more indulged than China in restricting the social media so the country built an internal internet. (Not connected to outside internet sources)
They might have different reasons for the censorship of the internet but everyone is unified under same simple common goal i.e; taking people’s freedom to access internet via social media platforms.
Here’s a snapshot of countries that are enemies of the social media apps & censors them till today.
