I think you misunderstand my comment. I know there are lots of advocates for OSH. But I don't think there is someone like Stallman who is advocating for free as in speech hardware the way Stallman does for software. I don't see the "social and ethical values" of the kind of freedom that Stallman talks about reflected in OSH discussions. However, I only see the English language part of the conversation, so something different might be happening in Europe/Italy.
