I always took it as a critique of generally using attractive women to lure in the nerd crowd ( the assumption being that boobs would boost sales which, if we're honest, they do).
Since it's a Star Trek spoof i can see it though.. sexism has always been there with Trek, even as socially progressive as it was. It just couldn't avoid the short skirts and tight fighting shirts and to cast attractive women with no real plan other than to have some eye candy for the show.
In one Q&A at a con i saw Marina Sirtis speaking about her role and she directly adressed this.. the producers on the show didn't have a clue for the first few seasons what to actually do with her and early on she was at high risk of actually being cut from TNG if not for Denise Crosby leaving.
Now i actually got a bit annoyed, maybe angry, and also disappointed when Seven was introduced.. on its own a cool concept having a Borg drone be freed and see her reintegrate into society but of course they chose a very attractive and curvaceous woman and put her in a skin tight bodysuit for the entirety of the show (and in the process they cut another female character who was no sex puppet). She became a really good character and Ryan played her well but to this day i'm still disappointed.
They basically did the same with T'Pol on Enterprise though not as obvious (she was "allowed" to wear normal clothes but still rather close fitting) but then upped the ante with the decontamination scenes
Thankfully Discovery managed to avoid this and i don't expect Picard to have some obvious sexualized roles so there's hope the franchise has put this in the past and moved on.
Disco has flirted with the concept on occasion: Captain Killy, Mirror Georgieu, Commander Nahn...
