This news was first revealed by The Verge and was later confirmed by Android Central. According to The Verge’s report, a WhatsApp spokesperson has said that:
Given recent discussions with various authorities and privacy experts, we want to make clear that we will not limit the functionality of how WhatsApp works for those who have not yet accepted the update.
The Facebook-owned messaging app revealed in its new policy that it will share more personal data with Facebook. However, the shared data will only be messages sent to business accounts that may be stored in its servers.
This has sparked a lot of controversies online and millions of users have shifted to other messaging apps as a result.
