Well first they support file uploads, second I feel like everyone I ever met from this instance was nice to everyone (sure that can be because it's smaller but it also has less controversies (i.e. what the dude I was replying to, the lemmy.world blocking us) due to the overall nature of this instance)
Went here for the file uploads, stayed for the community, that's what I can personally say
I'd suggest the switch for you
That is only maintained due to the new operating system being a new shell placed on top of the countless older shells and some new small features that rely on the newest most fragile thing they added with the shell
I heard some call it the "painting over rust" method, and they're maintaining the most used and by some organisations the most relied on operating system in the world
