Many subs are already opening up again sadly.

The subs going dark should have only been half of the protest. Users should have also stayed away from the site but I don't think that was really coordinated.

The number of new posts didn't drop much, the comments dropped a bit more but only by like 20%, which isn't a lot given the amount of subs that went dark. Reddit doesn't care about subs, they care about users and it seems engagement was still pretty high.

The next protest should be to all users to stop using the site. Drop the users and they'll start to listen.

Yeah when the blackout started I disabled my Reddit app and haven't been back there once since. We need more people doing this.
I went back to post on the "We're back from the Blackout" posts to go let them know about the new communities that were started up.
I did that for a few that I'm interested in and got downvoted immediately. There's definitely some bot like activity trying to flood content/organic growth on the communities polling/figuring out what's next, so that users would flock back. They are also pushing back on alternatives when a good ol person would be just curious/happy/relieved that there's some semblance of carry-over away from Reddit.
