Yes, if anything, IP owners should consider different business models that allow for such collabs / spin-offs to happen. I guess "integrity" / "quality" is somewhat an economic decision as well as it ties together with the value of the IP (usually completely unfounded projections of future loses). Like what Peter Thiel mentioned in his book Zero to One, having a monopoly works in one's favour of knocking out competitions, but the best kind of monopoly is creative monopoly, where there's a mix of competition & collaboration, usually in the form of a marketplace that gives the consumers more options to choose and be time-invested in.
