Over the past five years, the largest social platforms settled on a clear position about private messaging. Lock it down. Facebook turned on end-to-end encryption. Instagram and Messenger did the same. X joined the club. Yes, metadata is still an issue and the protocols used matter; but, generally speaking, the move was toward more privacy of actual messages.
TikTok looked at that trend and made a different choice. Then it scheduled a briefing in London with the BBC to explain the reasoning.
The explanation was safety.
In the UK, TikTok belongs to ByteDance, a Chinese technology company that operates under Beijing’s jurisdiction. China maintains strict limits on end-to-end encryption inside its borders. TikTok, after its own review of the issue, reached the same policy outcome for its messaging system.

Alan Woodward, a cybersecurity professor at Surrey University, raised that point directly. The company’s “Chinese influence might be behind the decision,” he said, adding that end-to-end encryption is “largely banned in China.”
TikTok declined to engage with that suggestion, of course. The remark hung in the air. However, it’s worth adding that the US operation of TikTok has made no indication that it is moving towards private messaging standards either.
End-to-end encryption is simple in theory. Only the people in a conversation can read the messages. The platform running the service cannot access the content. Governments cannot request it. Engineers inside the company cannot view it.
TikTok’s system operates in a different way. Messages on the platform remain readable to the company. Employees can access them under defined circumstances. Law enforcement agencies can request them through legal channels.
TikTok argues that readable messages allow the company to identify harmful activity.
The debate turns on a basic technical fact. “We can read your messages to catch predators,” and “we can read your messages” describe the same system.
The second statement applies to everyone on the platform. Every message becomes part of a structure that remains accessible inside the company. Employees can make mistakes, systems can face breaches, and legal demands differ across countries. Each factor creates another path through which private communication may be accessed.
