First subreddit over 10M to go private. The message shown when trying to enter the sub is a quote from spez:

I think the problem Digg had is that it was a company that was built to be a company, and you could feel it in the product. The way you could criticize Reddit is that we weren't a company – we were all heart and no head for a long time. So I think it'd be really hard for me and for the team to kill Reddit in that way. Steve Huffman, CEO of Reddit, April 2023
