So really, aside from his choice of words, he's not saying anything about this book that isn't equally true of every other tie-in.
After all, The First 150 Years
contradicts Pocket's post-ENT novels which predated it; yet my Rise of the Federation
novels are consistent with those novels and nobody told me that I had to ignore them and be consistent with TF150Y instead. And tie-ins always
have to be consistent with canon. Therefore, TF150Y is not canon.
