I like the way you've presented this as an in-world pamphlet, but I think it could lean more heavily into overt, unintentionally-hilarious propaganda. There are notes of satire here and there but I think there are missed opportunities to simultaneously tell the corporation's (transparently bullshit) of things while heavily implying what's actually going on ("Although we generously extended paid leave for amputations to 48 hours, protests continued, with cowardly terrorists throwing themselves beneath the treads of crawlers to delay essential caviar deliveries for the management gala." That's maybe too much, but you get my meaning.)
I also like that although you present an example scenario, it's not made clear which side the characters are likely to be on.
Obviously, this isn't totally usable off the shelf, as the scenario is more of a single scene, and perhaps more illustrative than prescriptive. But it seems like a useful supplement to weave into a homebrew adventure.
I see that others have bemoaned the lack of Mothershippian "horror" elements, which is true but doesn't bother me because, again, it's not a complete adventure, but material to be woven into one. I think using an insurgency as the backdrop to a more standard monster story would create something more than the sum of its parts. E.g. maybe the twist for a group that's inclined to side with the insurgents is that the shipment they're intercepting turns out not to be space caviar this time, but the MacGuffin the corp needed to stop the threat. Oops. Now what?
