alt Hacker NewsWhatsApp is end-to-end encrypted, that's probably* better than using Telegram.
* Unless you want to go into a conspiracy theory that all the Meta employees can see the source code and nobody has ever felt like whistleblowing about the backdoor Meta put into WhatsApp, that is.
WhatsApp obviously more encrypted than Telegram since later have no proper E2EE whatsorver by default and also sync all history from server.
Its still preferable to use Signal since now it actually supports numberless registration. Hopefully they will actually fee payable not via credit card at some point.
