This is NOT true. Message keys are never sent to the cloud in WhatsApp, no matter what. You’re referring to the optional backup that requires users to opt-in. This sends an encrypted blob of all your messages to Apple/Google, and WhatsApp holds the key (but not the data) to that. Both companies would need to cooperate to read your messages, and this is OPT-IN by default. This isn’t E2EE, but it’s opt-in by default. It also has nothing to do with the key exchange for E2EE messages. You’re comparing WhatsApp, with all messages end-to-end encrypted and where the only way to compromise that is an opt-in cloud backup, to Telegram, where the vast majority of people (anyone using cloud chats) do not use Telegram’s encryption. Full disclosure: I begrudgingly use WhatsApp. I really don’t like it. You’re spreading misinformation, though.

Google can read it all, and has revealed the chats to help the Govt in multiple high profile cases here in India.

With telegram, if you enable secret chats, it is never backed up to the cloud. It is a guarantee, unlike Whatsapp where you do not know whether your contact has enabled cloud backups Full disclosure: I begrudgingly use WhatsApp. I really don’t like it.
