Amnesty International set out to determine which technology companies met their human rights responsibilities in the way they use encryption to protect users online security. The research resulted in ranking messaging apps of 11 tech companies based on the use of encryption. Facebook did the best, scoring 73 out of 100 for WhatsApp and Facebook Messenger. The absolute worst in the privacy rankings were Tencent for QQ and WeChat, BlackBerry and Snapchat, followed by Microsoft for Skype. The future of privacy and free speech online depends to a very large extent on whether tech companies provide services that protect our communications or serve them up on a plate for prying eyes.”]
