I think people who speak no english don't end on Reddit in the first place. It had very few traction in France as a far as I know, and facebook groups would be the go to places for most people. So yes, members of /r/france and /r/de read and probably participate the other subs as well, and the whole point of /r/france and the variations is less to speak french but to have local discussions gate-keeped by the language. Same for Japanese communities, there's massive subs for anime an Japan life, and there will be small niche subs in Japanese only to isolate from the bigger group and paradoxically have a less filtered bubble.
