Probably a very polarizing question.
On the one hand, having most of the users and communities on LW causes technical issues (see this post), and also gives the LW staff too much power over Lemmy as a whole.
On the other hand, with 18k MAU on LW out of 47k (https://fedidb.org/software/lemmy/), every community listed there has a much higher chance of visibility compared to an alternative hosted on another instance
I mean, there’s only so much you can do when your upstream is developed exclusively in Japanese (to the point the code comments are also in Japanese) with a focus on adding Reversi and a Suika Game clone into the software instead of refactoring so the same piece of code isn’t duplicated in 10 different files split across the frontend and the backend and refuses to implement editing because they find it too hard when both major fork families (Firefish/Iceshrimp and Sharkey) have it and it works fine enough (alt text edits don’t federate, but that’s comparatively rare)
