Looking at all of my subscriptions, it looks like exactly one of them, /r/linux, is currently private. /r/bayarea previously was. Places like /r/debian or /r/AskNYC or /r/SandersForPresident or /r/osdev just don't care -- or at least, they care less than they care about keeping their community open. There's a post each on /r/Christianity and /r/Catholicism saying thanks to the mods. There's a post vaguely about the subject on /r/networking, but it veered into discussion about the community.
As I mentioned elsewhere in these comments, yesterday's issue was specifically about the tensions between large, default sub volunteer moderation and Reddit the company. Most of the subreddits I read are small communities without these problems. (And they don't see themselves at risk for being banned for harassment / political incorrectness / what-have-you, so they're not concerned about that, either.)
While that might have been true when you posted this comment, I have trouble believing that it could be true for anybody right now. At least a half dozen defaults have gone private an the majority of posts on the signed-out home page are about this story.
