A huge bunch of various talks and presentations that are only meaningful to someone who is already familiar with the project? No, that's far from clear and easily-accessible for someone who is not familiar with the stuff, and https://en.wikipedia.org/wiki/FreedomBox seems like the most reasonable available explanation for it. And yet, it's totally not enough.
I still don't really get what they do or what they want, and I really have to say that this kind of approach really doesn't endear random people to the project -- people, that might otherwise start contributing to it. It wouldn't take them much more than a day or two to explain it all on their website and make the project and its developers more approachable, but alas, I get the feeling they want to maintain their own, precious little clique instead.
