I don’t think Mike was advocating doing that or portraying it as a good thing..I thought he was suggesting this is sort of ruthless thing Disney might do. (i.e. if fan pressure forced Disney to make retrospective payments to comic creators, Disney would look for another, cheaper source of film material).
My reaction at time was...that Disney partly bought Marvel exactly because it does provide them with a healthy source of royalty free material, and realistically they won’t readily give it up. (i.e. Mike was theorising about a situation we are never going to see in this life.)
