Hopefully, this is a case of not knowing all the facts.
There may have been a credit-free license paid to SPT to take their images and put it in this book. If that is the case, they would have likely contracted a HUGE amount of $$$ from Haynes (good news if true, it will give them much-needed revenue to finance more new poster designs) - and it would make sense, as their artists are more suited to drawing pictures of 20th-21st century Earth vehicles, not 22nd-24th century starships. If the assets are available and you have the cash, why not use them as 3rd party contractors? Most non-Trek enthusiasts would never know the difference; only the more limited Trekker demographic like what resides here on this board would catch it, and it seems that, of late, whether the fandom likes it or not, Paramount has been trying to market Trek to the general populace for some time now.
So I will reserve judgment until more info comes out on what happened (as a rule, I generally don't like supporting plagiarists). I will still get the book, as it does sound interesting, and Trek tech books are few and far between any more, sadly. Let's let cool heads prevail until we get more info. The SPT people probably know about this board and, if they feel they've been wronged, either they or other parties "in-the-know" will say something - unless they have and I've missed it entirely (always a possibility).
