In Russia, we have a law that requires companies that own messenger apps, to retain and provide contents of messages at request or provide information necessary to decrypt the message (encryption keys). There is no responsibility for using encryption for end users, and for companies it is either a large fine or being added to a registry of blocked URLs. So it is difficult to enforce such a law in practice.
