I moved from Lemmy.ml because I liked the name of Lemmy.world and it ran a newer Lemmy version which meant I could make communities.
I moved from Lemmy.world because they defederated from piracy communities they didn't even host (but for some reason still kept the small piracy community they DID host)
From thelemmy.club because I couldn't see the Hackintosh community from there (probably defederated)
Now I spent some time looking on join-lemmy.org and checked out some instances and this (lemy.lol) instance seemed good, so I chose that.
Which is fine for you, but other people might not like existing on an instance entirely devoted to bootlicking and silencing any differing opinions (that are even left of mainstream… but not left enough).
People joining .ml should know what they’re getting.
