Scuttlebutt and copyright
I've been thinking lots about copyright over the past few years, mostly in the context of software and its source code, but I've just realized that I don't understand how Scuttlebutt (the social system) handles copyright. Can someone point me in the right direction?
I've been operating under an implicit [magical] copyright license what gives our peers the right to re-broadcast our feed, but I don't remember actually giving consent for that. Is this the case, or are we just trusting our friends not to sue us for copyright infringement? I remember some discussion between @andré and @elavoie a while ago but I don't remember think there was a conclusion.
Would it be wise to avoid replicating content we don't have an explicit copyright for? Or has this problem already been solved through some hand-wavey legal magic?
