Richard Stallman resigns from the FSF

There is a bare minimum consensus and even that's not universal. Most countries have such limits in place, but the wide variation shows that it differs a lot. It's not like that most people agree on that or what the nature of consent entails - some schools of thought / cultures require a marriage contract, others require affirmative consent etc.. I think the law, after having been relaxed quite a lot in the 60ies is now tilting to a more hard line stance in many western nations. It's constantly in flux. That doesn't happen a lot to other legal realms.
