Think this case in particular is pretty interesting. Former default subreddit and one of the largest on the site (Top 20 at least).
I think /r/videos is where we'll see how things actually play out with the reddit admins. I'm guessing at some point the admins will step in and replace the mods.
Yes, that's what it means. If you look under the names, you'll see "public" or "private." The way they are going offline is to make the subreddits private. The green ones are labeled private.
