In the original post his link refers to another post of him in Telegram which then refers to the Telegram FAQ (which i linked here directly) which talks about the Telegram encryption. This is all true (I don’t know about though so i can’t say anything about that). – In December 2020, the Wikipedia article about WhatsApp had the label “This article may have been created or edited in return for undisclosed payments, a violation of Wikipedia’s terms of use”. – WhatsApp Gives Users Ultimatum – Share Data with Facebook or Lose Access Let’s look at some of the arguments from the post on Telegram:

A friend send me a post from the founder of Telegram, Pawel Durow in which he explains why WhatsApp is bad/unsecure and Telegram is safe. The Problem is that they use misleading information about their own privacy/security. Telegram is trying to benefit from the current media attention focusing on the privacy/security issue and that’s fine. Because of the latest announcement from WhatsApp, many alternative messaging services experiencing a flood of new users. Most people now are aware about the problem with giving your private data to Facebook but some (many?) still didn’t know that WhatsApp belongs to Facebook or just never thought about the possibility of sharing data within the Facebook companies. While this is not new and since WhatsApp belongs to Facebook, everyone should assume that the data from WhatsApp is shared within the Facebook company. Facebook lately announced that they will share more data between WhatsApp and Facebook.
