Why do you think their plugins like EssentialsChat, EssentialsXMPP, and all the other side plugins are have been abandoned lol? Because it's not being maintained. Why are you comparing FileZilla? Totally irrelevant. They maintain their code that's why, where as EssentialsX has been left the way it is with few very changes, but its still bunch of bloatware like it has always been. There's nothing wrong with not using EssX. There are countless of warp plugins, tp plugins, economy plugins,whatever EssX has, that all do the same crap, just differently, and maybe better. & Code wise, it could defintely use some improvements just from looking at their Git repo.
