When I say corporations aren’t people, I mean that in a literal sense, with implications such as “corporations shouldn’t be given human rights” (I’m sure there are some rights which do make sense for both humans and corporations, but it’s not 1:1)
When I say corporations have motives, that is shorthand for “the human leadership of this company has motives which control their decision making and cause them to make decisions which point the corporation in a certain direction”
