I guess I didn't think 'use' meant 'use facts to make arguments to advance your interests'?

Like, I wouldn't say that I 'use' 'asymptotic complexity' to promote engineering priorities over product management. I read a lot of nefariousness in that phrasing, but I guess that's not what was meant.

I've certainly seen cases where people would "use asymptotic complexity" to, say, argue for a system that was better for their CV than one that was appropriate to the amount of data actually being processed. I did mean to at least suggest a certain amount of nefariousness; I think a lot of those who adopt intersectionality as a way of framing/approaching issues do so not solely out of sincere truth-seeking but because (consciously or otherwise) it makes it easier to reach conclusions that suit the upper classes and, perhaps even more importantly, makes it easier to avoid reaching conclusions that don't suit the upper classes.
