Excerpt:
Most major subreddits show a decrease of between 50 and 90 percent in average daily posts and comments, when compared to a year ago. This suggests the problem is way fewer users, not the same number of users browsing less. The huge and universal dropoff also suggests that people left, either because of the changes or the protests, and they aren’t coming back.
They were just religious ads, that would say things like Jesus loved his neighbors #hegetsus. The biggest complaint I saw about them was at some point, that was literally the only ad you would see on reddit.
