ABSOLUTELY AGREED.

In fact I think all now-dead authors should have their work as-is protected to a fair degree.

Dollars to donuts that the anecdotes revealed something either embarrassing or personally connected to the family members, it's just easier to posthumously blame the drinker.

I absolutely agree that shining light onto the subject of alcoholism is nothing but good for those seeking to avoid the horrible problem.

I wouldn’t say “should not”. That’s a complex issue and I wouldn’t say anyone is obligated to put painful moments of their personal lives on public display. Any family suffering from alcoholism has other examples to learn from, and they aren’t under any obligation to contribute another one if they’re uncomfortable doing so.

It's their call to make. They feel the chapters didn't represent their father and, as a draft, I would expect the later parts to have been less revised and to be in a rougher shape.
