It doesn't matter anyway.
A good copy can be better than the original.
In this case, I will tell you that I don't think that Satisfactory is better than Factorio. I was incredibly excited for the idea of 3D Factorio, but so far, it just leaves me asking, "What's the point"? It doesn't get me anywhere near as excited as a new build in Factorio.
If you want 3D Factorio just get Minecraft and a modpack like Omnifactory or Skyfactory or Gregtech New Horizons. Minecraft is something that easy to keep coming back because of the large modding community.
If you want want an economy simulation MMO then checkout prosperous universe.
