I am not aware of such an attitude in AES countries. Historically it was in fact quite the opposite, youth political organizations and organizations promoting an active lifestyle were encouraged and celebrated.
I think in principle there's nothing wrong with the idea, actually it's probably quite a healthy and socially beneficial thing. Of course that doesn't preclude the possibility that in some cases the implementation was not the greatest or that sometimes bad actors found their way into them. But those problems always exist with anything that you do, we're talking about the general principle.
And yes, as another comrade pointed out, FDJ and Komsomol were not scouting organizations, you're probably confusing them with the pioneers. Though the former also sometimes took part in activities of that type it was not their primary purpose.
