I've read a lot of ADF over the years, lots of puns, lots of world-building detail that other "older" sci-fi doesn't have. That typically means there's also some politics that doesn't age well as well.

I was assuming this would mainly relate to the indigenous population of the ice planet this trilogy is set on, but actually I think this does a good job of saying "well actually they can decide what they need" and there are various characters trying to exploit or support them.

The absolutely terrible part is the character of Colette, who is a fat woman. That's her character, she's fat. She literally can't be on a page without this being pointed out in description or by a character. It's weirdly remorseless.
