KBin has taken over Lemmy in monthly active users count
Looks like KBin has an edge over Lemmy now in terms of monthly active users.
It's obviously a pretty silly thing, and is not in any way indicative of which project is "better" or more "long-term viable" or anything — instances of both federate with one another, and with the rest of fedi, so it's all one happy family.
That said, it's notable. KBin is a relative newcomer to the "Reddit-like fedi instance" game, and also does not have the tankie baggage.
I don't think you need to worry about it. It's up to a given community whether or not that baggage affects it or not, I think. Building communities that are very explicitly not tankie is a great way of helping overcome that baggage for the whole project.
