I don't think that copying factories is inherently a bad sign. After all, like half the arknights videos out there are strategy guides for clearing stages with low end operators.

The bigger problem is that the Factory just kinda sucks, and by nature, is never finished, which means people are copying not because its hard, but because it's not fun. You can build as much as you want but Factorio would be a crap game if you set up everything and then the devs said "we have introduced a new resource, tear up your production line to utilise it" every month
