WhatsApp’s code is not public. The app generates the private keys. The app has to have access to the private keys to decrypt your messages. Because the code is not public, no one has any idea if meta has ad hoc on demand access to the private key, or if they upload the private key to their servers.
If WhatsApp was open-source like signal, we wouldn’t be having this conversation. Until then, and based on metas know business practices, it’s safe to assume they have access to WhatsApp private keys.
