I think the author is writing specifically about fashion and pop culture as a component of capitalism. The author would probably say that making pants for women was an effort to expand into a new demographic of customers, not to expand women's rights. Essentially, all movements are merely a product. Civil rights are the byproduct. And following that theory, the author predicts that LGBT culture, as a fashion product, will fade. For example, we'll probably stop seeing the force feed of obligatory LGBT scenes in film, to be replaced with obligatory <insert pop movement> scenes instead.
