I was under the impression that WhatsApp is a relatively secure messaging platform [1].<p>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.<p>[1] <a href="https:&#x2F;&#x2F;whispersystems.org&#x2F;blog&#x2F;whatsapp&#x2F;" rel="nofollow">https:&#x2F;&#x2F;whispersystems.org&#x2F;blog&#x2F;whatsapp&#x2F;</a>
