At this moment in time, there are several countries throughout the world, which tend to be extremely strict when it comes down to the freedom of using the Internet. Such examples include China, Syria, and even Turkey from time to time.
By imposing censorship, the governments of these countries wish to discourage access to information, and online meet-ups needed to discuss possible protests, ideologies and more. According to recent reports, it seems like the government of Turkey has recently blocked and restricted several websites including Google Drive, GitHub, Dropbox, Microsoft OneDrive and more.
This decision was made to stop the spreading of leaked emails, about Turkey’s President, Recep Tayyip Erdogan, alongside with his son in law, who happens to be a government minister.
