Do you trust Meta with your keys? One key 'feature' of WhatsApp (and iMessage for that matter) is that they also handle your encryption keys. This undoubtably makes life easier for people (messages can be easily restored/ported to another device) but it also means that ultimately the keys to your encrypted messages are owned by people who you cannot trust (i.e. Meta). And sure enough in a lawsuit against Meta it has been alledged that Meta actually can see your message content, and they scan it for their advertising and AI business, and for security agencies.
