Telegram has voice chats now and Discord is just terrible privacy wise.
Nearly all chats on telegram have the same level of security as discord. Only ‘secret’ chats are end-to-end encrypted. No group chats are end-to-end encrypted.
They tout themselves as secure because they use TLS for data transfer which discord does as well. The only difference is that if you manually enable a secret chat they can’t read those messages. They can read and listen to everything else.
And I didn’t mention security or E2EE in the post for that reason… just check the privacy policy of both apps.
Because a lot of Discord users won’t consider them good alternatives to it. Element is adding a feature equivalent to channels in Discord but it doesn’t have Discord’s voice chat.
