What will happen on May 15
WhatsApp on its FAQ page clearly states, “No one will have their accounts deleted or lose functionality of WhatsApp on May 15 because of this update.”
What happens after May 15
“After a few weeks of limited functionality, you won’t be able to receive incoming calls or notifications and WhatsApp will stop sending messages and calls to your phone,” notes WhatsApp. In other words, your WhatsApp account will become completely useless.
As clearly stated, users shouldn’t as WhatsApp will not delete your account but make it so useless that either you will have no choice but to accept its terms and conditions. Otherwise, there’s always Signal and Telegram, no?
