WhatsApp subscribers not exactly thrilled by the idea of sharing their personal data with Facebook
In a statement released to TheVerge, a WhatsApp spokesman stated that the company was reversing field again when he said, "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." WhatsApp also said in a support article online that "because the majority of users who have seen the update have accepted, we'll continue to display a notification in WhatsApp providing more information about the update and reminding those who haven’t had a chance to do so to review and accept."
WhatsApp says that those who have not yet accepted the updates will be able to do so inside the app. These opportunities will take place "when someone reregisters for WhatsApp or if someone wants to use a feature that's related to this update for the first time."
If you plan not to accept the update, before you decide to delete your WhatsApp account on Android, iOS, or KaiOS, there are things to keep in mind. "Deleting your account is something we can’t reverse as it erases your message history, removes you from all of your WhatsApp groups, and deletes your WhatsApp backups."
Facebook concerned about WhatsApp users leaving the messaging app for other secure rivals like Signal and Telegram
WhatsApp was forced to give up and give in in an effort to keep more of its members from jumping to other messaging apps with end-to-end encryption like Signal and Telegram. For the latter though, a "secret chats" feature must be enabled for every contact individually. By the way, you might not be aware that your WhatsApp chats are backed up daily to your phone's memory.
To back up your chats go to WhatsApp > More options > Settings > Chats > Chat backup > BACK UP.
