We can agree on the statement "Telegram does not cooperate with law enforcement authorities".
This is however something completely different from and largely orthogonal to "Telegram does not have access to their users' message contents".
The fact that they are consistently claiming the former and the latter makes them seem extremely untrustworthy to me.
Gaining my trust requires truthfulness and transparencies about the capabilities and limits of a service provider's technology (but of course is in no way sufficient).
