Every interaction I've had with mindfulness so far hasn't been that it was "sold", it was just simply offered. It's not an organized religion or ideology, from what I've seen there doesn't appear to be a hidden agenda. I've personally found it quite interesting to reflect on the subject of mindfulness and my (current) conclusions I have regarding how to live my life - there's a lot of overlap.
It's not something that exists to "help us cope with the ravages of capitalism". Political ideology aside, it's simply there to help you think and act more freely by understanding your thinking and acting. My friend who studies mindfulness says (para-quoting): "it's about understanding your actions and why you take them, it's about separating yourself from your immediate reality". I think most people could potentially benefit from such an idea. In general I believe people should take more time to "do nothing" and reflect.
As for being "the enemy of activism", if clear thinking is the enemy of activism, I think this says more about the current state of activism than it does about mindfulness. In general, I believe we shouldn't be striving to produce a society who dedicate their lives to activism. It's perfectly okay to be an activist, but there has to be more - life is short after all.
