There is no reason at all to believe that the dozens of definitions that study used for "factory farm" fits the few ones stated on that wikipedia link. And there is no overwhelming problem that applies to all of the few definitions on your wikipedia link either.
As your wikipedia link shows, people commonly describe as "factory farm" anything from places where animals go indoor in the winter all the way to places where the animals have no space to move. Or places that create a lot of sessile animals are placed. Or places where animals are gathered to eat. Or places engineered to be comfortable for animals that don't move a lot.
And that is only if you stay within the reasonable people. Almost everybody with an impulsion to talk about this subject uses unreasonable definitions. How is a single name that applies to all that still meaningful?
Fine, let’s say “factory farming” is not a useful term. Do you have any suggestions for how we should talk about / classify modern farming practices? I genuinely appreciate this discussion
