Honestly atm I'm using lemmy for mobile and kbin for desktop. I might switch to kbin more permanently if the app gets finished and is a better user interface. I'm mostly on lemmy simply because I'm mostly on mobile.
The personal views of the lemmy devs are bad, but by the nature of FOSS idk if that should matter. I also know nothing about the veiws of the dev of kbin, and I don't think I wanna know tbh. I'm not sure how I should behave in regards to the problematic political views of the people making things I like. Lemmy could always be forked and worked on by different people but that would probably only really happen if the current devs ruined it or abandoned it.
