I hate to defend Facebook/Meta but HN title is pretty blatantly missing context.

Even the linked post says:

> In most cases, law enforcement sends Facebook a search warrant or a government-issued subpoena for data. But Facebook policy also allows for “emergency requests,” where the tech giant will voluntarily hand over data outside of the legal process when police claim a case involves death or “potential bodily harm.”

So, it is unlikely that Facebook/Meta is just sharing your chat history over without just cause.

Regardless, you should be using Signal or WhatsApp for your chats anyways.
