While political engagement is an alternative to "slapping unbreakable crypto" onto things, this article establishes no precedent for political engagement actually helping!
I see the technical as political, direct action as engagement.
An article like this that's attempting to be a call to action, needs to provide some positive reinforcement. I find myself failing to come up with big wins, the examples I can think of are almost exclusively heartbreakingly tragic (snowden, manning, swartz, Occupy, etc). When I think of political engagement in the US, I think of pretty violent end cases for everyone involved.
