It’s a pretty commonly repeated theory amongst far right / reactionary “thought leaders”. They call it the “Long March Through the Institutions”. I think the comment you were responding to was ironically referencing it.
Anyway, what you presented is not a “gotcha”, despite the fact that I’ve heard it a million times when engaging with right wing “intellectuals”. It’s still a conspiracy theory.
I'm going to go out on a limb and say that a German student activist's definitionally anodyne proposal to engage with society and barely referenced in the decades since has probably been coopted more than a little to concoct a new boogeyman for the right wing.

as well as the lack of a smoking gun.
