Yes,  Discouraging.  I read 3/4 of Vultures to Vampires and it brought back all the memories of hopes that the Amiga would rise again.  I remember going through Commodore Bankruptcy, Escom, Gateway, Amiga inc fiasco.  Not much has changed.  I remember meeting Jason Compton and Eric Schwartz at an Amiga show in Dayton, OH in 1995.  Jason was giving a live update about the bankruptcy.  The book was good but VERY depressing!  I am reluctant to buy Volume II.
On a brighter note, I have built my X5040 and been using it months now.  I got notice yesterday from Acube that my SAM460LE will ship today or tomorrow.  Just waiting for the shipping notification.   So even if Tabor is not moving forward, others are.
