Don't have a copy of that and the only thing that stuck in my head from reading it once was that a disgraced and washed-up time cop's personal theory was that some outside source gifted the tech to them hoping that the Borg would use it against the Federation.
The "washed-up time cop" part is staggeringly incorrect. I think you may be confusing it with the incompatible portrayal of "Dulmer" and Lucsly in the
Star Trek Adventures tie-in novel. Both Lucsly and Dulmur were DTI special agents in good standing when they discussed the matter in WTC, immediately after interviewing Picard in the wake of
First Contact (an interview established in
Section 31: Rogue).
However, the rest is roughly accurate.
I'm guessing your beef with it was that the Borg aren't usually that creative and/or that they're sacrificing a lot of tech just to subjugate one enemy?
Partly. Mainly it's just logic. If the Borg had time travel capability at all, then they would already have used it to assimilate the entire galaxy. I mean, from the Borg's perspective, the Federation is small potatoes, or it was until
Destiny. It's a remote power on the far side of the galaxy from their territory, tiny in comparison to them. They could easily just bide their time and get around to assimilating it when it was convenient. If they were willing to use such an extreme tactic as time travel to deal with such a minor adversary, then surely they would use it routinely and the galaxy's history would've long since been rewritten in their favor. It just doesn't add up that they used it that one time, to deal with what was then a relatively minor nuisance from their perspective, but never in any other context.
As far as the Borg being given time travel tech or not, there's a good argument that they assimilated the knowledge they needed all on their own.
Which is why I suggested in WTC that the temporal-protection agencies of the galaxy have collectively worked hard to prevent that from happening. FC was a case where something slipped through their net.
As far as it being out of character for the Borg to use time travel to salvage a botched mission, that might hold water, expect that the Borg Queen herself was in charge of the operation and she does have a record of thinking outside the box and doing more creative stuff then the Borg root command defaults to
That's a specious distinction. The Queen herself said it in FC when Data asked who she was: "I am the Borg." The Borg Collective is one
single consciousness. It isn't a race or a nation or a society or a crew. It is
one mind existing simultaneously in every drone, every cube, every nanoprobe. The drone that we call "the Queen" is merely the central coordinating node for the collective thought of the rest, like the frontal lobe of the human brain. And at times, the Collective uses the Queen body as the face and voice it speaks through, the same way it used Locutus as its face and voice in BOBW. The Queen is not a separate being from the Collective any more than your mouth is a separate being from your arms and legs and heart and brain. It's the part that speaks, but it speaks for the whole.
Heck, in "Endgame," we specifically see the Borg Queen overrule the Collective's initial plan to just assimilate Voyager the moment they find it again to watch and wait for something more crafty.
The same scene in which the Queen
verbally addresses her drones, which is missing the whole point of a collective consciousness. That scene was one of the most idiotic moments in the franchise, proof that the producers were burned out and phoning it in and not thinking it through any longer, lazily writing the Queen as a stock Evil Leader rather than remembering what she truly was in relation to the Collective. No way am I going to weigh a moment that stupidly written over everything else that canon established about the Borg.
But the scene can be salvaged by interpreting it as a dramatization of a single mind debating within itself, weighing its options before choosing one. In this case, it's like reflexively reacting a certain way to a stimulus, then catching yourself and changing your mind when you think it through more carefully.
As far as why the Borg never use time travel much, I do like the LUG RPG All Our Yesterdays' notes on the subject; since the First Contact mission was an utter disaster, it would make sense that they'd tread carefully and reconsider their plans for Earth, even the Borg can't calculate all the wibbly wobbliness of changing the past, and that later that year, they needed the Federation to survive up to that point so they wouldn't get wiped out by Species 8472.
It's solipsistic to assume that FC was the
first time the Borg ever tried time travel. They're supposed to have existed for millennia! They've assimilated cultures far more advanced and powerful than the Federation. That's how they got so big and powerful in the first place. So if they had time travel, surely they would've had it long ago, and they would've rewritten history to absorb the whole galaxy long before the Federation ever existed.
(Also, if we consider all tie-in accounts as equal, Engines of Destiny complicates the "Borg were given time travel tech," since that novel is pretty clear that the Borg were operating within their natural means and the TNG/Doctor Who comic crossover establishes that the Borg decided to get time travel tech to be able to deal with the Doctor on his own terms after their alliance with the Cybermen went south.)
It has never been the practice of
Star Trek tie-ins to depict a shared, mutually consistent continuity. Some subsets of them do so from time to time, but only within themselves. There have always been cases where different tie-ins explore distinct, mutually incompatible interpretations of a given event or idea.
To contrast against Christopher's opinion, though, I think the Borg are smart enough to NOT mess with the timeline for their own gain genuinely. They're a clockwork species and the idea of having to screw with casualty is something that they, unlike we stupid monkeys, is a monumentally stupid idea so I assume they'd only do it as a last resort. Indeed, I'm assuming that they had to have seen something in the future that justifies such an extreme response on their part.
I think that's giving the Borg far too much credit. They have no judgment or restraint, only insatiable hunger. They are a sentient cancer, compelled to expand and absorb. They're actually quite stupid in the main, because they only have this single driving impulse that's all they ever think about. They will do anything to feed their hunger, to increase their power and spread.
And if they fail at something once, they don't think "Oh, let's not do that anymore." That's not how the Borg operate. They try it again in a new way. And if they fail again, they try again in yet another new way. And they keep methodically trying again and again until they've adapted to every obstacle and achieved their goal. They never get impatient, never despair and give up. They just adapt and repeat. They should not be anthropomorphized, not be mistaken for a race or a nation that thinks or acts like normal humanoids. They are fire ants, expanding relentlessly through an ecosystem until they've consumed everything within it.
