If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that’s for the future of us all.
You are right. Lemmy and Mastodon are user-centric while Funkwhale or Peertube are more on the artist/creator. For this reason I encourage people to use these sites, supporting artists who decide to use these platforms.
