Freedom House has conducted a study on internet freedom in 60 countries across the globe.
What the authors of the study found is that global internet freedom has deteriorated in the last three years as a consequence of the increase of laws and regulations that try to limit free speech on the web.
An estimated 34 countries have seen a decline in internet freedom since 2012 including Vietnam, Ethiopia, Pakistan, and Venezuela. On the other hand, 16 countries have seen an improvement in internet freedom, among them Morocco, Burma, and Tunisia. Despite those improvements, limits on internet freedom are still rampant in many countries that make the list, where censorship, threats, and murder of bloggers and users who post information governments see as a threat continues.
