This objection has become questionable in view of the fact that, in advanced industrial society, the technical apparatus of production and distribution functions, not as a sum total of mere instruments which can be isolated from the social and political context without losing their identity, but rather as an apparatus which determines a priori the product as well as the individual and social operations of servicing and extending it, that is to say, determines the socially needed demands, occupations, skills, attitudes – and thus the forms of social control and social cohesion.
I have tried referring to https://www.merriam-webster.com/dictionary/a%20priori, the closest possible definition I got is
2 b: formed or conceived beforehand
Thus, can a priori in the aforementioned text be interpreted as:
... determines beforehand the product as well as the individual...
