Being trained as a media theorist I understand your criticism (and am going to check out Horkheimer's essay, thanks for the tip!).
But this website purposefully tries to keep things accessible in order to reach a wider audience.
I often see how academics have a deep understanding of what's going on, but just aren't as good at spreading that insight to a wider audience, like the startup community.
Still, I think it's useful to point to some of the academic backing--like you already do with Foucault, just perhaps in greater depth. Maybe add some of that academic/conceptual source material to the further reading section--then again, might just distract from the main point. You know your target audience better than I do, I only have my particular reaction (which is probably a bit idiosyncratic and outside of the scope of your intended audience).
In any case this is a cool project and a noble effort. Hope you stick with it.
