The key change is that WhatsApp will be sharing its lists of users' phone numbers with Facebook, allowing the company to match up WhatsApp accounts with Facebook ones where users have registered a phone number. That will give the parent company more data with which to make new friend suggestions and another way to target advertising.
One thing that won't change is who can read your WhatsApp messages. With newer versions of the app, they are encrypted end to end, so only the intended recipient can read them, the company said.
In its relations with regulatory authorities, Facebook and WhatsApp are damned if they do, and damned if they don't. Facebook has been roundly criticized in the past for collecting too much information, particularly about people who don't use its service, or are not logged in, through "Like" buttons on third-party websites.
On last Tuesday, though, French and German lawmakers said that messaging services such as Telegram and WhatsApp that offer end-to-end encryption don't keep enough information about their users' activities. The French and German interior ministers called for operators of encrypted messaging services to provide a back door for law enforcers to tap into users' messages in the course of investigations. That might lead to leaking or misuse of information by foreign governments and hacking or spying scandals, which may shake the foundations of secrecy and freedom of non-exposing the private data on the Internet, especially if we know how easy is to hack a Facebook profile, or someones' cell-phone. Although, the WhatsApp doesn't cost any money, would you like to pay the cost of your privacy?
