WhatsApp subscribers not exactly thrilled by the idea of sharing their personal data with Facebook
WhatsApp uses end-to-end encryption
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.
