Did you even read the link you put in your comment? reddit did not "censor" anything. We simply fixed the the algorithm that was accidentally ranking that reddit too high. It was never popular enough to be in the top 10.

At the time you censored the atheism subreddit, it had just about as many subscribers as the other top 10 subreddits at the time. You decided to arbitrarily change the algorithm until it seemed right to you.
"we added the ability to prevent certain reddits from appearing in the top ten"
The number of subscribers is not the metric we used. We use a metric we call "activity". The behavior described in that blog post simply pointed out a bug in the activity metric.
Also, to be pedantic, it is not possible for reddit to censor anyone. Governments censor things, private entities do not.
To be pedantic, censorship is not limited to the government. Being private does not let you avoid the label of censorship.
And yes I know the metric is called "activity". It is just too suspicious that you let it rank well all these years and let it disappear from the front page just because a far smaller subreddit (by subscriber) was on the front page.
