The only issue with WhatsApp (I have no idea about Signal) is that, while it offers seamless encryption, it doesn't allow you to use an alternative client. Therefore, all trust has to be placed in the client and its distribution to ensure it doesn't mess up (intentionally or not). For the average Joe however I totally agree with you and it's a good baseline.

Security folks, especially on HN, are very actively hostile to alternative implementations and clients because in their mind it breaks security. Just see any Apple or Signal topic.

The walled garden lockin in by design for you to be safe.
