I understand that this is not an attack on DH. I have not analyzed telegram but the statement I quoted seems to indicate it would need to be able to quickly generate many DH params. That doesn't seem to be a a computationally trivial task.

It seems like for this attack to be realistic you would need the math underlying DH to be broken somehow. At which point I think there are many applicatons who's security would be compromised that are far more disturbing than the security of telegram.
Again I am asking for clarification because I may be misunderstanding the use of the quoted text and I have not looked at the code myself.
As I read it, this analsis seems akin to someone stating that, a wall provides no security if we lived in an alternative universe where solids could freely pass through one another. That statement maybe true but who cares, that universe wouldn't continue using walls for security measures anyways. Excuse my metaphor there, I hope it clears up what I was asking about.
