Except that Taylor is symbolically Titania here, she pretty much is the mother of the Fae, considering she created them (or at least created the LA fad with them).
Bah! Those are just light-weight Tolkein-flavoured humans. Wood elves, at best, who have lost contact with their From Over The Sea heritage. You need to look at things like dryads and nymphs to see what lower-grade fae are like, or some of the stranger Japanese supernaturals.
Look to Celtic legend, and Old English bits, for the true Fae (or some Japanese full-blown Kami), the ones who wear a human form like a convenient cloak, and think just about anything human is, at best, amusing. And, if you're a bit unlucky, annoying. Or, you've just broken some deadly rule, which to them is 'obvious'. And, as a result, they can explore just how far they can go with fates-worse-than-death.
It would be... bad for Taylor to become one of these greater Fae. Gram might approve, but I'm pretty sure Taylor'd enjoy her life a lot less.
All those things Taylor should easily see. It should make sense to taylor why Grams might offer her a smidgen of help, even excluding familial ties.
Because in pretty much any other situation, a corpo would either offer taylor a deal like this, or more likely cage taylor or threaten her. Not just throw her loose.
Took me a while, but I suspect I know why Gram+Taylor's behaviour doesn't make sense to you...
You are assuming humans are rational.
They aren't.
This is one reason why traditional (neo-classical?) economics doesn't work. It assumes rational behaviour - the '
rational economic unit'. You might want to look at Kahneman's
prospect theory.
Also, if you look at the reasons people start companies it is rarely for financial purposes. Yes, you
need to make money to keep things going, but that
is not the initial motivation. In fact, once 'money men' take over a company, that's often a really bad sign, and its days are numbered.
This interacts in fun ways with the 'ultra capitalism' of CP'77. In many ways the whole corp thing is being used as a social structure. The money is secondary. There's some strange abstract tribal stuff going on, 'in' and 'out' groupings. Arguably, 'nation', another abstract concept, is playing the same social games. One reason some say 'never trust a nationalist', possibly because even
they may not be sure what they're talking about.
So, what Taylor and Gram do or don't do about the BD/sleep-minimiser company
is not about rationality. It is inter-personal power politics. Evolutions of primate posturing (arguable mammal pack behaviour). Survival logic.
Rationality? Try getting an AI, on each side, to negotiate? Fail. Because those will, at base level, have been created by humans. And, if they don't work in a human-compatible way, they'll never be used, will be junked.
