WhatsApp isn't E2EE by default either, since default flow pushes you to backup your key to Google Drive. Signal isn't E2EE, given the security blunder in which private images from your gallery were sent to random contacts (which indicates a scary state management situation in the apps, this isn't easy to do). E2EE implies that you purposely send content to specific people which is encrypted, not that your app sends potentially embarrassing or intimate pictures to your boss behind your back. That blunder is unforgivable.
