I actually think I agree with this, but nevertheless people can refer to EA and mean by it the totality of sociological dynamics surrounding it, including its population of proponents and their histories.

I actually think EA is conceptually perfectly fine within its scope of analysis (once you start listing examples, e.g. mosquito nets to prevent malaria, I think they're hard to dispute), and the desire to throw out the conceptual baby with the bathwater of its adherents is an unfortunate demonstration of anti-intellectualism. I think it's like how some predatory pickup artists do the work of being proto-feminists (or perhaps more to the point, how actual feminists can nevertheless be people who engage in the very kinds of harms studied by the subject matter). I wouldn't want to make feminism answer for such creatures as definitionally built into the core concept.
