After all these years, security researchers still don’t know if the encryption is any good?

On that level it usually falls on computer scientists. Formal methods can prove that any implementation is correct, but proving the absence of unintended attacks is a lot harder.
Needham-Schroeder comes to mind as an example from back when I was studying the things.

And not a single one has been able to analyze the encryption in all these years? Fact is, Telegram is the tool the Russian opposition and even Ukrainians use to communicate without Putin being able to infiltrate.

No. It kind of falls on Dijkstra’s old statement. “Testing can only prove the presence, not absence of bugs.”
You can prove logical correctness of code, but an abstract thing such as “is there an unknown weakness” is a bit harder to prove.
