Hm. Political Commentary in a show is hard to pull off. And as Huggs said, those issues were already in the universe and where handled with nuance so why mention it?
As far as politics in shows go... Doing it the way Battlestar Galactica, or Stargate SG-1 did is fine and fits. It's a balance. BSG/SG1 hit right within their respective universes. But the worry here is, in modern times, when a writer focuses any part of their interview about politics then it's a red flag, a warning sign like going on a date and the guy/woman yaps about how all his/her exes are the problem while shifting his/her tone without reason (You can prolly guess he or she has a temper and isn't faithful.)
But I'm worried what is meant to be "Aliens: Earth War 2.0" will end up being "Humans bad, Men bad, white bad, Democracy is evil if it doesn't let us starve families like Stalin did, more Mary Sue's like Wesley Crusher and Rey Skywaler! reeee" and other weapons grade Twitter shoutouts just to spark more flames of hatred in society (Thankfully, those types of people are a small minority of media tryhards and not a majority.) I wouldn't be surprised if he turned the Colonial Marines into psychopaths that all have a combat jack after gunning down civilians or go over the top with anti-everything steryotypes.
In short, I don't trust him to have nuances, individuality, and growth with characters; instead I'm worried it'll be copy paste "Goons" and one dimensional characters just written in to make political statements.
*Inb4 someone gets mad at me: I'm not trying to start a fight, I'm an egalitarian, and despise racism/sexism. But those topics don't need to be shoehorned into a movie or show, because doing so kills the fun, horror, sense of reward, etc of the movie/show as you watch beloved characters grow from zeros to heros.*
