That data seems wrong. I don't use Reddit much, but I checked the data aginast some smaller subs I sometimes check, and according to those charts they have just a few comments per day, but I know for a fact that's wrong.
It's wrong for all subs I checked. For example: https://subredditstats.com/r/thethickofit
Just 3 comments for Nov 22, 8 for Nov 23. But how does that square with the existence of this thread from Nob 22 with 84 comments? https://old.reddit.com/r/thethickofit/comments/181d68u/ben_s...
And there's a bunch of other threads too! It's not just "a little bit wrong" it's completely wrong. That site seems about on the ball as a dead seal.
The end result was a stalemate. Reddit did not change any of its policies. Enough of the people responsible for posting and managing content left the platform to cause a noticeable impact on it.
Here's a fun thing to look at, https://subredditstats.com/ for any major subreddit, e.g.:
https://subredditstats.com/r/worldnews
https://subredditstats.com/r/explainlikeimfive
https://subredditstats.com/r/videos
All of the most popular subreddits show a steady decline from 2019 to present, with a sharp drop in July 2023. Once this happens to a platform, it's rare for the platform to ever get those users back at scale. It's safe money that Reddit will now be a zombie platform, a la Slashdot -- still up and running with some users, but with flat or declining activity forever.
