When push comes to shove a majority of these moderators would rather hold onto their perceived fiefdom for some form of semblance of power and control in their life than growing a backbone, standing up for what they say they believe in and deleting their account in protest.
If you want quantified numbers I suppose you could view charts like
https://the-federation.info/platform/184 <--- Bunch of tabs at this site
https://the-federation.info/platform/73
https://github.com/LemmyNet/lemmy/graphs/commit-activity
https://codeberg.org/Kbin/kbin-core/activity/daily <-- Not sure how to generate nice charts from this one
But frankly, if you need me to tell you this, you aren't remotely qualified to write that article.
Would you like me to retort to saying that I am incompetent to write this article? I don't think you would like that very much.
For me it's just a last straw on the camel's back. The site has obviously gone severely downhill since pivoting from the old.reddit.com desktop-based site that focused on links and discussion, akin to a forum, to what it is now, an infinite scroll of half pics and gifs, half rage-bait. There is not much interesting discussion going on on Reddit these days, the change of the UX to prioritize mobile use has changed the entire nature of the site to favour short quips and less thoughtful posts. People on this board will often say things like "oh well at least if you go to your specific niche subreddits there is still good discussion being had", but even this is much reduced. Go to any long lived historically discussion-heavy board like say /r/Coffee, /r/LetsTalkMusic, /r/TheoryOfReddit, etc. If I look in the internet archive and go back 10 years, I generally find much more interesting conversations being had back then.
This latest debacle killed that goodwill for a lot of us. Why bother contributing -- through moderation, posts, or even upvotes/downvotes -- to a site that clearly doesn't value the rest of us?
On the bright side, HN has continued to host decent conversations for years running now. There are a few decent communities growing on Lemmy, Tildes, and Squabbles as well. I'm excited for the distributed future, I think the Fediverse is going to provide a lot of decent competition in terms of hosting, UI, and moderation over the next couple of years. It's much needed after almost two decades of stagnancy from Reddit.
