You cannot refuse this. If you were to actually read the policy when viewing it, you would see that you have the following options:

1. Accept policy or
   2. Stop using WhatsApp

Most people are not aware that the “new” policy is exactly the same as it was 4 years ago, except for commercial users, that is, companies that use WhatsApp to communicate with their customers. In 2016, there was an option to unsubscribe from the mailing list, and people who chose it at that time still chose it, but the choice disappeared soon after.

Deleting your account and moving to similar platforms will not change anything now as your data is securely protected by WhatsApp as you agree to the new terms of service.

If you delete your existing WhatsApp account and create a new one, that won’t fix this problem either.
