The Facebook-owned messaging service has been hit by a global backlash over privacy. Many users are migrating to Signal or Telegram. Should you join them?

Earlier this month, WhatsApp issued a new privacy policy along with an ultimatum: accept these new terms, or delete WhatsApp from your smartphone. But the new privacy policy wasn’t particularly clear, and it was widely misinterpreted to mean WhatsApp would be sharing more sensitive personal data with its parent company Facebook. Unsurprisingly, it prompted a fierce backlash, with many users threatening to stop using the service.
