As we all know What App's had done some changes in its privacy policies, which become a very big topic of debate in nowdays. People are very concerned and worried about their privacy as the new updates bring a hole in the privacy system of  What App's. So as their are a lot of fingers risen on What App's other messening apps see this as a opportunity for them to grow more. And in this Race their is involvement of the World's Richest man Mr. Elon Musk.  Mr. Musk tweeted on his handle "Use Signal". 

Signal is a cross-platform encrypted messaging service developed by the Signal Foundation and Signal Messenger LLC. It uses the Internet to send one-to-one and group messages, which can include files, voice notes, images and videos. It can also be used to make one-to-one and group voice and video calls, and the Android version can optionally function as an SMS app.

Signal uses standard cellular telephone numbers as identifiers and secures all communications to other Signal users with end-to-end encryption. The apps include mechanisms by which users can independently verify the identity of their contacts and the integrity of the data channel.

Signal's software is free and open-source. Its clients are published under the GPLv3 license while the server code is published under the AGPLv3 license.  The Android app also includes third-party components which are closed-source. The non-profit Signal Foundation was launched in February 2018 with initial funding of $50 million from Brian Acton. Signal has more than 10 million downloads on Android.

Signal is not commonly used by common people. It is used by the journalists and other Politicians as it is very safe and secure and that's why after the What App's conflict , Signal has created it's pace in the market.

Elon Musk tweeted "Use Signal" on Thursday, which led to a huge number of signups for the app, after WhatsApp made changes to its privacy policy. WhatsApp will be sharing more data with its parent company Facebook, which has raised a lot of concerns. Earlier today, Musk also tweeted a 'domino effect' meme, where he implied that the start of Facebook was responsible for the chaos and violence that took place at the US Capitol in Washington. It's perhaps no surprise that Musk has a history of public disagreements with Facebook founder Mark Zuckerberg, which often get aired on Twitter. Signal is a well-known privacy- focussed messaging app, that is widely used by security experts, privacy researchers, academics, and journalists around the world. The Signal protocol also underpins WhatsApp's end-to-end encryption, although one key difference is that Signal is open source, while WhatsApp is not.

As Signal is a open source too so there is also questioned are raised about it that it is safe to use. So yes it is a open source but the privacy and security system is well built and are more better than the What App's new policies. WhatsApp's updated privacy policy and terms of service have new sections including Transactions and Payments Data as well as Location Information. The most notable changes that exist on both updated privacy policy and terms of service are around how WhatsApp shares information with Facebook and its subsidiaries.

As mentioned above, this wasn't the only dig that Musk took against Facebook. A little earlier, he also tweeted a meme connecting the starting of Facebook to a domino effect leading to the violence and chaos in Washington. Musk has a history of disagreeing with Zuckerberg on Twitter, that goes back many years now. The two have, for example, famously disagreed on artificial intelligence, that Musk argued had to be carefully regulated. When Zuckerberg had spoken against fear mongering over AI, Musk tweeted that the Facebook CEO's "understanding of the subject is limited."
