I think BeeHaw when trying to be a welcoming community and disabling down votes is shutting itself in the foot (e.g. the large numbers of users joined those instances of lemmy, but BeeHaw users could do nothing when they started attacking them.
The upvote only works well when the community is small or when you want to tune the network into increasing engagement (see Twitter, Facebook, YouTube, they know that users not being able to downvote will cause controversial topics go up, and those cause higher engagement).
I am divided, because I also feel like you that maybe this is too much and feels like I'm now needing another account to be able use other communities, but I also do appreciate the effort to trying to have a friendly community. I do think long term this will be harder and harder to manage though...
