Or they just could make the scenes be part of the story so if you don't choose it didn't happen and is not referenced in game. I agree with you on the point it doesn't matter if you see or not if the game says that happens well it happens.Or, counter point, the absolute least authoritative source of what Studio Fow promised in the past would be studio fow in the present.
Followed closely of course by VValen, the Fow Stan with his easily documentable discord track record and thread behavior. We have the screen grabs, archives, and pre release promotional material saying otherwise. And all the other media sources shared and fostered to say things "they didn't say" that directly led to backer perception and support.
Some of the new "descriptions" also make the "no NTR" (nonplayer sex in front of the player current tag definition) thing even more a lie in the face of "(paraphrasing) the captain's away so now I have to fuck these tentacles" and other such gems. On top of the fact nothing is optional, just not unlockable. Some of the new descriptions make that pretty clear it's happening and you as the captain must be viewing it after the fact. The equivalent of not having to watch a certain red horned demon pay your wife a visit. Different strokes, but considering the captain has a "I cucked you fair and square" world view, he in narrative would view himself as a cuckold over the goings on in his own ship even if you the player are just along for the ride as a 4th wall observer. (People also generally don't like a character done dirty like that, but this gets into the writing and it's whole other set of issues.)
Didn't have to be like this either. Wildlife has a nifty solution, in their storymode it's strongly hinted you're going to ultimately become a beastman and you'll be able to watch all the scenes from a first person PoV and/or player perspective. Sandbox play you already can pilot and play the beast characters. Other games roll out a similar "you have a new body and/or were always a dragon and/or..." narrative framing that makes the player or a player foil the one getting laid in most content (that think subverse unilaterally lacks)
They had the perfect solution here too, you the genetic progenitor of all the mantics pilot them in battle and they're otherwise passive and nonsapient as stated. The whole "living bred weapons loyal to one commander" plot is kind of wrapped up in this sort of thing. Easy framing from there is first person/3rd person PoV monster sex of the player as the monster. Considering the fact the target demographic of Fow content was and still is furries/beast enthusiasts many/most people would probably have preferred the captain as a means to one end: having a dragondildo dong via such a narrative framing.
It could have been part of this update with the little dialogue descriptions in leu of actually making the scenes contextual, which would have explicitly made mantic sex MC content and interrelate it with the combat playloops. Instead here we are.
The idea that the MC can turn on the xenos is ok if it is an option. But they chose to say “No we just going to deliver what we intended not we marked”
