Article summary

WeChat, a popular social media platform in China, conducts pervasive content surveillance on communications conducted entirely among non-China-registered accounts. This surveillance is used to build up WeChat's Chinese political censorship system, and files deemed politically sensitive are used to train and update the system. The platform's censorship features were previously thought to only affect users with China-registered accounts. WeChat's content surveillance and censorship practices have significant implications for users' privacy and freedom of expression.

What commenters say

• iMessage and WhatsApp are considered more secure than WeChat due to their end-to-end encryption, but their security is not foolproof.
• Relying on companies' goodwill for security and privacy is naive, and users should be aware of the potential risks.
• Even with end-to-end encryption, metadata can still be accessed and turned over to authorities, compromising user privacy.
• The security of messaging apps depends on various factors, including the trustworthiness of the company, the openness of the source code, and the user's own precautions.
• Some argue that no system is completely secure, and that security is a matter of degrees of trust and risk.
• Others emphasize the importance of open-source software and cryptographic verification to ensure the security and integrity of messaging apps.
• The fact that WhatsApp's founders left Facebook over disagreements about data privacy and security raises concerns about the company's practices.
• Ultimately, users must weigh the benefits and risks of using different messaging apps and take steps to protect their own privacy and security.
