you don't have to be a drugs. This is a fairly standard position. IF they claimed they wrote it, or if they claimed you approved it, that would be fraud and should be processed as such. But if I were to present "@delric's book presented by @Fu" that is a morally legitimate move. If I happen to be better at publishing, marketing, etc. and the market prefers my version so be it. However historically being first to market is the most important point in determining which is preferred by the market.
@Fu @delric It's the same if I slave away on a piece of software or report. After 2 years it loses its value and nobody cares.
