The problem is that the fluff doesn't sell. Having the crunch subsidize the fluff, is something I'm 100% okay with.
With that said, Data Trails is terrible and I really hate that book. I don't think fluff and crunch need to always align, but it sure helps a lot when it does. DT has too many things in the fluff with no rules or clearly break the rules, and that's a core book and not a novel. I can sometimes handwave problematic stuff I read in novels like Frost and Fire or Dark Resonance where a host can fit in a box, which clearly breaks the rules and can't be done, but whatever. But it's really annoying with DT, the book ABOUT the Matrix breaks its own rules in the fluff.
The fraggin' Matrix... It's really annoying that it as a rule system still doesn't work and that people have no idea how it works.
