This is dual-edged: as technical communicators, we create and consume materials that serve to further knowledge and learning (or impact business interests). This naturally leads us to be participants in social and political interactions, or rather democratic interactions, like Herrington mentions in this article. I feel that the need to create content or develop solutions (to problems) is often driven by economic, social, or political problems.
Another point to be made here is that as technical communicators, our emphasis lies on creating content for our audience to use. We want our content to be for the users' benefit, the authors' benefit is of lesser importance.
