Even if companies were forced to publish every detail of their devices (which is the only way to not have trade secrets), any decently complex products products would still be black boxes to every company who is not specialized in creating them.
Even something like a fountain pen is used as a black box, I'm not even talking of anything truly complex. Even the buildings we work in are black boxes that we get from third parties, not to mention all the systems powering and heating or cooling them.
