WhatsApp promises to protect every one of its 2 billion users with end-to-end encryption that ensures their messages cannot be seen by anyone outside of the original conversation. But does it live up to that promise?

A new report alleges that the Facebook-owned messaging platform uses artificial intelligence and more than 1,000 contract workers to examine “millions of pieces of users’ content” using “special Facebook software.”

That’s despite Facebook CEO Mark Zuckerberg telling the U.S. Senate in 2018 that “we don’t see any of the content in WhatsApp.”

WhatsApp has updated its app requirements, meaning that all users must now run at least iOS 10, as released in 2016.

That means that iPhone 4s users can no longer run the popular messaging app. Instead, anyone who wants to use WhatsApp must have an iPhone 5 or later. Otherwise WhatsApp will stop working.
