How is /r/firefox still private?

/r/running had a poll and most people went for indefinitely blackout. A few days later it went public again. I tried to ask what was going on with the plan but the post was immediately removed.

It appears that Reddit drove out the mods and put in new mods. But I am glad to see the majority had gone and not much new posts about running.

Now I wonder how/r/firefox can still be private.
