Indeed, KRAD is thanked in the acknowledgments for his assistance to DRGIII in writing Revelation and Dust. The idea that this is all "punishment" against KRAD is just silly.
KRAD was thanked previously. While his books were being ignored/at best, swiftly neutered at the request of TPTB.
You're letting wishful thinking colour your perception.
In what sense were his books being "ignored" or "neutered?" Which books were so "ignored" and "neutered?"
His last ST book, A Singular Destiny
, featured President Bacco and introduced the Typhon Pact, which he co-created with Marco Palmieri. President Bacco has since appeared in twelve books that I know of; the Typhon Pact has literally had its own series of novels encompassing eight titles. The governmental system KRAD designed for Articles of the Federation
has been featured in numerous books published since A Singular Destiny
, from Christopher
's DTI: Watching the Clock
and DTI: Forgotten History
, to the numerous DRGIII DSN novels. And now, of course, one of KRAD's most important characters has become in death the apparent centerpiece of the entire Fall
miniseries, and the constitutional processes KRAD developed for how the Federation government functions promises to play a huge role in subsequent novels.
If they're trying to retcon KRAD's books out of continuity, they're not doing a very good job of it.
