I was under the impression that WhatsApp is a relatively secure messaging platform [1].

I travel, from time to time, to countries such as the UAE, Singapore and France. I once attempted to get people to use Signal. No luck. HN seemed to have arrived at a consensus that Telegram is a crock of shit. So I shifted - in part due to local adoption - to WhatsApp. When their in-app calling was blocked in each of the above countries, I gained a little faith in their security model.

I think this might be relevant. Especially the last paragraph.

> In interviews with journalists WhatsApp stated that they would use Public Key Encryption, where only the sender and recipient can unencrypted content. Indeed they did, but they used the same key for every user.

Wow.

I would venture to guess that in-app calling is disabled (in the UAE) to protect teleco revenue streams.

When texting on WhatsApp gets blocked in the above mentioned countries then you'll know it's secure.
