I'm not speculating at all and I think you're misunderstanding the point I'm trying to make. First of all, transport security (server-client encryption as you called it) like TLS is irrelevant for this discussion. All major platforms on the internet employ transport security these days, so this is a given. The point I'm trying to make is that Telegram does not offer E2E encryption by default: (Non-"secret") Messages on Telegram pass through Telegram's servers unencrypted and are also stored there unencrypted, meaning that Telegram has access to all your messages. This is not speculation – Telegram openly admits to this in their FAQ: https://telegram.org/faq?setln=ru#q-do-i-need-to-trust-telegram-for-this-to-be-secure https://telegram.org/faq?setln=ru#q-do-i-need-to-trust-teleg... (See also the link contained therein.) Meanwhile, the speculations in the present HN discussions aside, WhatsApp does provide E2E encryption, so – from this POV – is orders of magnitude more secure.
