Privileged women have obvious and legitimate self-interest in trying to ensure women's control over their own fertility. But social justice will require much more of the privileged than that they share their birth control, and historically it doesn't appear that there's been much willingness to pay those costs. I am optimistic that we are in a moment when that willingness is increasing,  and I'd hope that raising these matters would help a little, to that end. 

Absent an equally fervent commitment to social justice, criticisms of birth control as bearing a eugenic taint will, unfortunately, continue to have some legitimacy. That's just baked in, for as long as society discourages and de-values the lives of poor people of color on every other front.

Anyway, that's how it seems to me. All the best.
