OpenSUSE adopts a new code of conduct

It's standard American philosophy in this situation - in the American view, the only thing that prevents you from killing someone without consequence is that the state will take action against you that is at least as damaging as your gains from the killing. But, if the state actively kills you (e.g. the death penalty, "accidental" shooting by the police and other such things), there are no consequences for the state or its constituent parts for the killing.

In this model, it's right and proper that the state be limited in ways that companies aren't, because companies aren't given the same powers as the state, and the state will use its power to restrain companies. And note that for the early European settlers of what became the USA, the contrast was to absolute monarchies in Europe, where you could be prosecuted and put to death for treason if there was a viable accusation that you'd spoken against the monarch's policies (e.g. on religious belief) in private.

All that said, this model comes from the tendency to treat the state as an independent entity, adversarial to the people; this makes for "simple" theories about how the state should be controlled, but it's not a great model of reality. More modern philosophers tend to see this as excessive simplification, and it's from those more modern philosophers that the European Convention on Human Rights comes, where freedom of expression (a more general concept than freedom of speech) is protected in balance with other baseline rights (like the right to privacy, and the right to not be tortured). But the founders of the USA were on the leading edge of human rights philosophy 250 years ago, and it's not surprising that things moved on in the century and a half between their day and the ECHR.
