Is Lemmy.world centralization worth fighting against?
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
History of LW controversial decisions
when they promoted Discord as an official communication channel (https://lemmy.world/post/3478399 - since then they created a Matrix chat)
when they realized centralization of communities on LW was impacting the ability of other instances to stay up to date (https://lemmy.world/post/13967373 )
Indeed, I use it from time to time, but from my experience, it seems like LW users tend to stay on their local feed, increasing the visibility of their local communities compared to ones from other instance
