Of all the subs I was subscribed to, there were I want to say only about 10 that didn't take part in the blackout. I unsubscribed to all of them. I am now subscribed to only subs that either took part in the blackout, or in one case one that opted to remain public (due to the nature of its contents) but is blocking all submissions for the next couple days.

For me, once RIF stops working, reddit will be dead to me. I will never install their official app, and 99% of the time I'm on reddit is on mobile. I have no doubt that old reddits days are numbered as well and that was the remaining 1%.
