No is not fine, open a thread like this when the game is out and you can judge the content and the writing of game.
I think it's okay to offer concerns before the game is released.
The real issue is that the OP has done little or no research on even the basics of the gameplay trailer. EDIT: CORRECTION, I did not read the OP's original complaints closely enough. His comments seem to be specifically targeted toward the skin color of player characters. I'd still argue the side characters show signs of agency, at least as much as "hackable robots" are capable of agency. I'll keep my analysis up though because I still think the trailer is rather racially diverse, which is a nice sign.

It starts off at 0:08 with a black (or darker-skinned) robot singing.
The next series of faces we see at 0:30 is a poster. The poster has 3 faces, two light skinned and one darker skinned. (The middle may be vaguely asian? It's not clear). At 0:32 we see the same poster, cropped.
At 0:36 the next face we see is a black (or darker-skinned) android. You see the neck of another android in front but I'm honestly not sure whether that is light skin in shadow or dark skin.
At 0:38 we see a light skinned android walking with a shovel, with another light skinned robot in the back. At 0:39 we see a robot of unclear skin tone, but it appears to be the same android we just saw.
At 0:41 we see two new androids, both darker tone, shoveling.
At 0:43 we see two new androids, lighter skin in front and uncertain skin tone in the back.
At 0:45 we see a light skinned android (maybe an ad)
At 0:46 we see a darker skinned android.
At 0:53 we see a darker skinned character (seems a protagonist, or at least a playable character for a segment). I THINK this character is an android since it can infect the others but I guess its not 100% confirmed. At 0:55 we see a light skinned android.
So within the first minute we have seen 7 androids with darker skin tones, and 8 androids with lighter skin tones, and a handful of uncertain skin tones.
Later at 1:21 to 1:22, when they look inside the store, we see what seems to be 9 androids inside, 5 to 6 of which seem to have darker skin tones.
At 2:56 there is a shot of the room full of newly awakened androids. Of the 9 androids in the shot, 5 of them seem to have darker skin tones.
These side characters also seem to have some agency. At 5:12, it is a darker skinned android that gives the player character a gun. At 3:10, it is a darker skinned android that replies affirmatively "we're with you!" I'd also like to note that when they look inside the store, the darker skinned androids do not seem to be put "in the back shelf" or appear as "clearance models", but rather are front and center (with some standing on raised platforms above the lighter skinned models).
Personally, I'd be much more concerned if all the robots were black. That seems like it would have the potential to become a game about reliving or reenacting oppression for the sake of enjoyment. I think there was a Resident Evil game a few years back that had some concerns about this, if I recall.
