Elon Musk tweeted “Use Signal” on Thursday shortly after making changes to WhatsApp’s privacy policy. This should increase data sharing with the parent company Facebook. Earlier today, Musk tweeted a “domino effect” meme, stating that the launch of Facebook was responsible for the turmoil and violence that broke out at the US Capitol in Washington. Perhaps not surprisingly, Mask has a history of public feuds with Facebook founder Mark Zuckerberg, which is frequently broadcast on Twitter.

A signal is a well-known privacy-focused messaging app that is widely used by security professionals, privacy researchers, scholars, and journalists around the world. Signal also supports WhatsApp end-to-end encryption. But one of the main differences is that Signal is open source, while WhatsApp isn’t.

WhatsApp’s new privacy policy has raised many concerns as the app long ago announced that there is no visible user data. And that WhatsApp is safe and private. Earlier, WhatsApp complained that Apple’s App Store privacy tag was anti-competition because the same label does not apply to Apple’s own apps.

WhatsApp’s updated Privacy Policy and Terms of Use include new sections such as Transaction Data, Payment, Location Information, and more. The most notable changes in both the updated Privacy Policy. And Terms of Service are how WhatsApp shares information with Facebook and its affiliates.

As we mentioned above, these weren’t the only digs Musk did on Facebook. Not long ago, he also tweeted a meme that linked Facebook’s start to the domino effect. Leading to violence and turmoil in Washington.

Musk has a history of opposing Zuckerberg on Twitter, stretching back many years. For example, the two have publicly opposed AI, arguing that Musk needs careful regulation. When Zuckerberg spoke out against the fear of AI. Musk tweeted that the Facebook CEO “has a limited understanding of the subject.”
