Signal: What Is It and Why Are People Leaving WhatsApp?
Use Signal — Elon Musk (@elonmusk) January 7, 2021
It begs a question, what makes Signal worthy of such a valuable tweet from Elon Musk?
To those who values privacy, Signal puts that on top of its list of pros.
The main difference is how Signal handles their encryption compared to WhatsApp. Unlike WhatsApp, Signal is an independent nonprofit. Which means that instead of earning revenue using advertisements, they use donations.
Signal lets you send messages and make calls via the Internet. Signal’s USP is its focus on privacy. It supports group chats and group video calls too. Signal is open source and its code is peer-reviewed, which means that its privacy and security is regularly checked by independent experts.
Signal was created by Moxie Marlinspike, an American cryptographer. The app as we know it today is developed by the Signal Foundation and Signal Messenger. Signal Foundation was founded on January 10, 2018, and a former co-founder of WhatsApp — Brian Acton — made an initial funding of $50 million.
The Signal app is available on Android, iOS, Windows, Mac, and Linux, although you can only sign up via Android or iPhone. Once you have set up an account, you can link Signal to your iPad or your computer, and use the app even if your phone is switched off. You can download Signal via this page.
I’ve always felt it was weird after chatting with my friend about buying a new bag, and suddenly the bag appears on my Facebook and Instagram ads.
In short, here are the list of pros and cons for Signal:
Deletes metadata automatically in photos
Independent company, nonprofit
No automatic invites to groups
Delete chats anytime
Contents are kept internally in your phone
Limit of 150 people in groups
Not all of your friends using Signal
Doesn’t work with Mac ecosystem
No backups for chats
Though Signal is rather new, it has a long list of pros that might entice us to make the jump and start using it. But rest assured, as long as it is a nonprofit app, it will be my number 1 messaging app!
