The owner of Facebook has gone beyond our notice to link WhatsApp and Facebook together so that any chat you made with your friends, love ones will appear on Facebook for everyone to see...When I saw this on a WhatsApp group, I thought this might be a sign of end time. But I quickly remembered its earlier updated end-to-end encryption. In case you have no idea about it, WhatsApp end-to-end encryption won't allow anyone except your chat mates to view your chats i.e everything becomes fully your property without nobody tracking your chat logs.
In addition, WhatsApp stated that "We plan to share some information with Facebook and the Facebook family of companies that will allow us to coordinate more, such as to fight spam and abuse, and improve experiences across our services and those of Facebook and the Facebook family". Also, "nothing you share on WhatsApp, including your messages, photos, and account information, will be shared onto Facebook or any of the Facebook family of apps for others to see. This means, that information will not be seen by other people on Facebook."
Is there still any cause for alarm?When it comes to any tech companies, I would not give a 5 star trust to their promises. If there has been some needs to sharing my mobile number and name to other companies in partnership with Facebook, then I'm opting out.
WhatsApp might not be the first tech company to share users data, what about our local service providers? When you come across any sms from short code numbers (33100, 3329 and others), they are just for promotional purposes.
