I think you’re looking at this too individualistically. They’re framing this guideline as being about protecting the dignity, reputation and legacy of the deceased, and I don’t think that’s a lie, but at the same time, it is an actor’s union and they’re going to care more (quite reasonably I would say) about living actors being able to make a living, than a surviving family being able to make some free money from a dead actor’s legacy. And actors having to forever compete against an ever-increasing number of ghosts of their forbearers goes counter to that.
