I think there are two aspects to this...
- The majority of people on federated message boards (lemmy, beehaw, kbin, etc) are former Reddit users who migrated specifically because of actions by Reddit, so it is natural to talk a bit more about Reddit at least for a short while. I believe this happened for quite a while on Mastodon (Twitter) as well.
- It's kinda fun to watch a dumpster fire in action ngl and I don't think this will pass until Reddit finally figures something out themselves...
