Optimistic Heroism vs Ruthless Pragmatism is the central theme for the Atlas arc's conflict, it's a fundamentally different view of how to save the world between the main cast and Ironwood. Another way you could look at it is Messy Emotional Reality vs So-Called Cold Hard Facts
Let's just call Fixing RWBY's handling of this theme to be.....lacking
The Ace-Ops are Ironwood's hand-picked team of elite fighters, and naturally they will reflect his own beliefs. They weren't partners at the academy or anything like that, they were put together because they're the best huntsmen in Atlas' military and have semblances that are complimentary on paper
Team RWBY was formed by basically pure chance. Between the eye contact rule and duos being put together based on which chess pieces they picked, there's no way to know what sort of people combinations you'll get at Beacon
Due to their military professionalism, the Ace-Ops insist that they're just coworkers that don't care about each other, how emotions will only get in the way of their teamwork
Team RWBY are true friends and a found family. They may argue and disagree with each other at points, but they love each other all the same and will stick together through thick and thin
During the V7 training / mission montage, we're shown a scene of the Bees and Marrow. Marrow suggests they work with their other teammates, in part because he thinks their fighting styles aren't very compatible
The Bees prove him wrong. Whether or not their fighting styles are "compatible," they're one of the best duos in the series because they know each other that well. Marrow focused too much on the raw logistics or "facts," completely missing the completely human element of Blake and Yang's relationship and trust in one another
Ironwood insists on keeping the secret of Amity entirely closed, nobody outside his immediate circle can know because of the risks of sabotage that might happen if it ever became public knowledge. Even if this hurts his reputation among the public, he thinks a damaged image is worth the reward of restoring global communications
The main cast thinks it's for the best that people know about Amity. His secrecy is actively hurting him because people not knowing the reasons for his actions is deeply hurting his ability to actually go through on finishing Amity
Ironwood believes that Salem's lack of humanity is the reason she's so effective. The belief that because of her lack of fear or hesitation, that acting just like her with monstrous cruelty is the way to beat her
Oscar fundamentally disagrees with this notion. If they retaliated to Salem's "lack of humanity" by acting the same way they'd be no better than her
When Robyn starts to steal the resources that Ironwood is repurposing, Mantle also stops selling the resources until Mantle gets repaired. He considers enacting martial law and he decides to arrest Robyn. Either force her and Mantle to cooperate or stomp out the problem entirely so he can continue Amity as planned
Blake and Yang decide to inform Robyn about Amity, hoping that learning why Ironwood's doing this can make Robyn stop without needing to arrest her
Ironwood considers neglecting Mantle and squeezing it completely dry to be worth it to restore global communications. He doesn't give a damn about them, to him they're only "a few city blocks," their suffering is nothing for the rewards gained
RWBY and especially Nora are completely against Mantle's treatment. They focus on the very real human element of the suffering the common folk are enduring because of Ironwood's policies
When the riots in Mantle start and a grimm army invades, Ironwood doesn't want to send in his ships because it "would leave Atlas vulnerable"
Upon hearing that Salem is at Atlas' doorstep, Ironwood decides to send Atlas to the atmosphere and abandon Mantle, even though he has the resources and was planning to evacuate all of Mantle mere hours ago. He refuses to bring in Mantle's people because of the possibility that one of Salem's agents is hiding among them, something that he's completely wrong about by the way. Cinder and Neo are already in Atlas, something Ironwood's sort of aware of with the queen chess piece, Tyrian and Watts have been detained, and Salem Hazel Em and Merc are flying in Monstra. Nobody in Salem's faction is in Mantle
The main cast choose to fight for Mantle, refusing to abandon its people no matter how much harder or riskier it may be. They even come up with a plan that is able to save almost everyone in both cities by the end of V8. I say almost because there were definitely civilian casualties from Cinder when she entered the void but they had no way to know she used the lamp to anticipate their plans
After Ironwood turns his back on Mantle the Ace-Ops repeat a sentiment akin to "Save who you can." When asked if they would save one of their members if they were in the same position as Oscar they say they'd abandon them because "Risking three lives for one is stupid," they would abandon them in a heartbeat and "replace" the lost member as fast as possible. In other words give up. Don't even try. Think of the "big picture" and "save more lives in the long run." Putting in any effort other than the bare minimum is a risk not worth taking. They're playing numbers games with people's lives
Obviously the main cast disagrees. Volume 8's opening is called For Every Life after all, they're trying to save everybody period. Ren outright says that "No one is replaceable"
Winter tries to rationalize to herself that abandoning Mantle is for the greater good to save Remnant as a whole, even though she agrees with Penny about hating this decision personally
Penny meanwhile "Fails to see what is good about any of this" and abandons Ironwood entirely after gaining the maiden powers
When Winter is falling to her death and Penny saves her, she says her life doesn't matter. She thinks Penny should have left her to die so she can keep chasing Cinder to stop her from getting Fria's powers
Penny simply saved Winter for no other reason than it being the right thing to do
Ironwood wanted to guarantee that Winter would be his next maiden. To do so he completely isolated Fria from the rest of the world and made sure only Winter was allowed to see her
Instead Penny becomes the maiden. She forged a brief but genuine connection with her. No manipulation, no isolation, nothing like that
Rather than try to compromise with the main cast and save Mantle so that they'll listen and agree to his plans, Ironwood decides to hack Penny. Force her to obey him with mind control. Fuck her free will entirely, he wants that staff yesterday and he knows best DAMMIT
In complete contrast to the main cast trying to save Mantle, Ironwood eventually decides to bomb it. Hold an entire city hostage to get what he wants. People call this character assassination but they're stupid. He's already signing Mantle's death warrants by abandoning them when Salem is mere hours away from arriving at Atlas. He's just making it much more direct now, and at least a bombing would be fast and painless compared to the grimm
Winter completely failed to gain the maiden powers by Ironwood's plan. However, it's after she turns her back on him that she finally does. Penny cared enough about her that she was in her final thoughts as she died. As opposed to Fria who Winter was simply using to try and gain her power, her genuine connection with Penny is what gifted her the winter maiden powers
When Winter gains the maiden powers Ironwood says "So the destiny I chose for you has arrived," as if somehow it was his plan that caused this, a complete insult to Penny's memory. Winter responds "You chose nothing. This was a gift," a big final fuck you to Ironwood's controlling behaviors and wrapping this theme in a nice little bow. It wasn't Ironwood's heartless plans or manipulations of others that gave Winter the power to save her own life, it was a simple human connection between people who care about each other
You may notice a lack of Fixing RWBY comparisons in this Fixing RWBY post. That's because Celtic doesn't tackle this theme in his rewrite. At all
Strike Team 32 as far as we're aware was formed similarly to how Beacon forms its own teams, we're never given any details on them being made for "tactical, pragmatic" reasons or anything like that
When RWBY bring up telling Robyn about Amity, they get shut down because "convincing anybody of the truth is difficult" and "politicians twisting the truth to their own ends is in their nature." They never even try to tell her due to this
Ironwood's treatment of Mantle is almost never brought up in the story. Hell he doesn't plan to abandon it, at least not yet
Ironwood's plan to guarantee his maiden by isolating Fria goes off without a hitch because Penny was the plan from the start
Celtic Phoenix's various rewrites in FRWBY focus so much on pragmatism, being "smart," and "realism." Whether he realizes this theme exists in canon or not, whether or not he realizes this trend in his writing, the way he writes is antithetical to this theme and RWBY as a whole. He fundamentally AGREES with Ironwood's approach, which is why Ironwood is never challenged in this way in FRWBY
