I think what those people mean when they say that is that it hasn't materially changed anything for most people, unlike what some reforms (or revolution) could do for people. They see it as a form of tokenism which they think historically hasn't helped much. Personally, I see both sides. I think this is actual progress that will indirectly have positive material benefits while also recognizing we can obviously do better than this.
