Yeah, tbh with all of what has happened on both of platforms, it's sad to still see them alive.
Hopefully, people slowly start moving across or they're some huge outage that happens in the future as it doesn't seem like many more people are willing to move across (at least from my experience).
Who knows, Threads may help the future of the Fediverse with the amount of users that could see the possibility of it across Mastodon, Lemmy and many other instances.
