This gives me the same feeling as all these old Prince recordings from his vault coming out. On one hand it feels wrong on the part of the family/rights owners to release this stuff against the wishes of the deceased, but on the other hand I really want that forbidden media.
Contrast Prince with Terry Pratchett, whose estate followed his wishes of destroying the hard drives containing Terry's unfinished works with a steamroller.[0] [0] https://www.theguardian.com/books/2017/aug/30/terry-pratchet...
I'm happy that Max Brod published Kafka's works against his will that they should be incinerated.
One never knows.
