Who owns the content of MO, and why migrating a question is legal? There is a long list of comments in Migrating a question which is already posted on the other site, and an important question is deep in that list, so I repost it here. Where in the legal agreement, < is it written that migrating MO content to m.s.e. is legally allowed? A more general question: who owns the content of MO, and what does "ownership" mean? Can the content of MO be sold?
