Lemmy and kbin share communities, https://browse.feddit.de/ doesn't show any kbin insances currently but that could probably be added fairly easily, if the dev wants to.
kbin is quite new so there's not gonna be a large amount of instances, resources, stat sites and so on.
Yes, many have come out and said that they simply won't be able to properly moderate once third party apps die.
Yep.
Hopefully a large amount of moderators and contributors keep staying away from Reddit, that'll drastically lower the quality of the site and thus their money making ability.
I'm definitely staying away.
Fedia seems to be having federation issues too, like kbin.social.
Which is very unfortunate, makes it hard to recommend or use kbin at all.
People are great at getting used to things, just give it a few days and you'll have figured out the fediverse.
I don't think reddit will backtrack at all.
