The update does not in fact affect data sharing with Facebook with regard to user chats or other profile information; WhatsApp has repeatedly clarified that its update addresses business chats in the event a user converses with a company’s customer service platform through WhatsApp.
For 5 years, WhatsApp has shared certain information with Facebook, including your phone number, unless you were one of the select few users who chose to opt out of data sharing while the option was still available that year. WhatsApp does not, however, look at people’s chat messages or listen to their phone calls, and WhatsApp conversations are end-to-end encrypted to protect against those abuses.
Despite this, a pop-up informing users of the new change included mention of how WhatsApp partners with Facebook, and it also included an ultimatum instructing users to delete their account if they chose not to agree to the new terms. That gave people the idea they were being railroaded into new, more invasive terms.
Facebook executives, including Instagram chief Adam Mosseri and WhatsApp head Will Cathcart, used Twitter to try to clear up the confusion, it seems with little success. Facebook’s poor privacy track record, and the fact that WhatsApp has over time turned its sights on monetizing the platform for its large international user base, has eroded trust in the chat app, which, in turn, has had the effect of turning a relatively mundane update into a worldwide controversy.
WhatsApp says it’s now going to use this three-month delay to better communicate both the changes in its new policy and its long-standing privacy practices around personal chats, location sharing, and other sensitive data.
