You're in the realm of politics, but politics is still not the front-and-centre focus of your story. You're not telling a political history; but you need to reference politics in order to explain the timeline, or situations of when one of several equally good solutions "won" and such. It is still a history of the technology and not political history.
This site is a perfect example. It presents itself as a technical forum where politics is occasionally tolerated but never the focus. And yet you could probably write an entire book about the politics behind the name of the site itself, never mind its history, rules, culture, and means of support.
