I’d like to point out that Project Xanadu (which, btw, is still going on) is, at its core, an attempt to solve this attribution problem permanently (at least for all good-faith actors) by focusing on quotation as a primary factor in composition (seeing editing as a form of selective quotation and rearrangement from previous drafts, for instance). Every so often I see articles like this (or articles on similar topics like music credits) that point out how necessary this tech still is — this clearly-skilled guy would still have his job if, by default, copy and paste between applications implicitly kept source attributions.
