I heard about this on NPR this morning (which is looks like someone already posted the link: https://news.ycombinator.com/item?id=39633900), and it sounds like the sons justification was that the book was good and the issues was that Gabriel García Márquez's wasn't in the right mind to recognize his own work anymore.

    "When he said it doesn't make sense he didn't realize it didn't make sense to him anymore."

I'm not familiar with this work so have no stake in this particular game, but it sits uneasy for me anyways. For myself, I think it mostly comes down to the incentives for releasing it.

Is this a valuable literary work that deserves to be published? How would we even go about deciding such a thing, without breaking the deceased's will anyways?

Or, is this just the estate saying, "The money from the previous books is drying up! We can either get real jobs, or go against dad's wishes for free money." In which case, screw that.

But even if you agree with the latter, given the complexity of the former, I feel like the fix there is that the rules for publishing works of the deceased should be different, e.g. it is immediately in the public domain so that there is no (or at least less) financial incentive since the original author has already decided not to profit from it. That would at least let us address the former questions more clearly and with reverence.
