Amidst the fury against WhatsApp’s latest policy, the App that has jumped to the top is Signal. The App proclaimed in a tweet, that it is the top downloaded app on App Store. It has witnessed a mounting surge in new users, due to which it is experiencing technical difficulties for new accounts verification and is resolving the issue to accommodate the extra capacity.
The spotlight on Signal is also attributed to Telsa CEO, Elon Musk’s tweet “Use Signal” to his 41.5 million followers on January 7. The endorsement is backed by the likes of Twitter CEO, Jack Dorsey and renowned American whistleblower Edward Snowden.

Issues with data sharing
WhatsApp has run into controversies about user data shared with Facebook and has triggered a global alarm about the safety of user data.
However, in a statement on January 12, WhatsApp clarified that the policy does not affect the privacy of messages sent to friends and family. It clarified that the update would include changes related to messaging a business on WhatsApp, which is optional, and provides further transparency about how data is collected and used. The data shared with Facebook is used to help refine services for personalizing features and content.
WhatsApp has published a new FAQ page on user privacy in response to the widespread backlash over the upcoming policy update.
