By using words that are closely associated with that context. This particular article goes even further, using words usually reserved for humans (or animals) to talk about software itself:
"[...] Objective-C was liberated. [...] when and how programming language software is liberated. [...] keep the core operating system of Android liberated."
>But you can't go from "you have rights" to "that's a claim of Human Rights."
And I did not. I specifically complained about the misuse of the terms "freedom" and "liberty". I have no problems with "rights". Quite the contrary, I value my rights as a user of open source software. But they are different, less important, rights than my fundamental human rights like freedom and liberty.
>You are imagining what people think [...]
Well, you know, that's the only thing language can ever do. Make people imagine what you think.
[Edit] Apparently I'm not imagining too much. Richard Stallman himself says it very clearly here: https://fsfe.org/freesoftware/transcripts/rms-fs-2006-03-09....
