Honestly in my eyes the issues with the White Fang/Faunus/Blake storyline are pretty easily addressed, cos its not an issue of realism, revolutions often end with the worst person in charge and rebel movements are often coopted by malicious foreign interests. The issue is more about narrative and subtle world building details, but that also makes it easy to address, though be it this is with the benefit of hindsight but:
Volume 1
1: During the news broadcast swap out the picture used with one of the Police harming Faunus protestors to show that while the coverage is bias in favor of the humans/against the White Fang reality is different.
2: I'd make Cardin's bullying of Jaune less extreme to contrast it with his bullying of Velvet, so slightly less emphasis on Jaune and more on the people around him's relative reactions.
3: Have Blake give a firm no to Weiss on the White Fang wanting to destroy humanity, forcing her to backpaddle to "They want to destroy my family."
4: When Blake is explaining the White Fang to Sun have her reference them protecting Faunus property & businesses from attack & breaking up trafficking rings to show why they are beloved and seen as a positive force by Faunus and how their recent change is out of character.
5: During Blake's confrontation with Roman have one of the White Fang soldiers say something like, "Just walk away, Sister Belladonna, you want not part in this." to show they aren't all onboard.
6: Make it clear that Weiss's shift with Blake is more tied to her realizing she was using the Faunus as a scapegoat in regards to her father.
Volume 2
7: Make the speech with Roman and the Lieutenant more mutual and shared between them.
8: Have some of the Faunus in the audience show visible injuries, & have it coincide with the speaker shouting out about the police to show who injured them.
9: Emphasize on the train how confusing the plan is, how it makes no sense that they would be doing this while having Oobleck look a little shifty about it.
Volume 3:
10: Give Sienna a static picture cameo with her watching the attack on Beacon and snapping "What is that fool doing!?" when Adam is on screen to show the high command were not in on this.
Volume 4:
11: This is where notable changes need to be made, but mostly just cut one Sun scene for a Sienna scene where she meets with the Belladonna & Blake, apologize obliquely for Adam's treatment of Blake and says she will end him once she has found his 'backers'.
12: When discussing their relationship with Kuo Kuana, emphasize that the White Fang protects lots of Faunus settlements that are neglected or abused by human Huntsmen and forces, hence people being so Leary of being against them.
Volume 5:
13: Have it be referenced Sienna has dispersed most of their forces to protect various settlements and Faunus abroad who are being impacted as a consequence of Adam's actions.
14: Major change here, but have Sienna survive through one means or another and when Adam calls for back up from his forces for him to hear her over the radio basically saying "No" causing him to freak out. Maybe have Leo have referenced some elder Grimm gathering in the area too and reference Sienna and her WF killing them so they can't reinforce Cinder and co.
Volume 6:
15: Wrap it up by establishing Sienna & Ghira are tag teaming the council, with Ghira offering military aid to protect Mistral territories but Sienna demanding the council begin changing laws and enforcement protocols.
Conclusion:
And boom, with only relatively minor changes the White Fang's popularity is more justified, they are given more depth while not removing the realistic corruptive and self serving elements, while emphasizing the harm they do and let them reach a reasonable resolution that can be expanded upon later without needing to observe it.
