Don't the Ancients have a lot of reason to hate people like Lugh and the ones working with him?
Many of the Ancients were cast out of their "promised land" by those people and force to flee to Seattle where they end up living in dumps, joining gangs to be safe and have a chance at some food... No?
It's varied from edition to edition. Particular Ancients (like GL) were exiled, yes. Others (split with the Laesa) have more recently been refugees, yes; but keep in mind those refugees could have been leaving the Tir for any number of reasons, so classifying them is hard (some could be diehard pro-Tir holdouts who aren't happy with how the coup went down, some could be love-all-metahuman types that left the Tir years and years ago because it was too elfy for their liking). There have also always been strong signs of the Ancients using Sperethiel to communicate, and integrating Tir-style rites and rituals into their own gang initiations and intergang rivalries, suggesting a favorable impression of things back in the Tir.
At times it's been hinted -- or outright stated, even, but I don't have books with me here on campus to cite anything -- that a whole bunch of them are ex-military (which makes sense given the Tir's mandatory service), but also that many are specifically specops types (and given the quasi-mystical side of oaths and ranks in the Tir, being a Ghost means being pretty damned loyal to one Prince or another). Also, you've got to look at their history of successful smuggling (guns and people in particular) in and out of the Tir; logically there's no way they could have done that without connections high up, and those connections have been mentioned before. The presence of a chapter inside the Tir doesn't explain away that level of success, given the page after page about paranoid border security back in the Tir's golden age.
Some are disgruntled exiles, but some aren't. The ones who are pissed off and cranky about it are fine with being pissed off and cranky, the ones with high-up contacts
use those high-up contacts, so that while the rank-and-file may or may not
care in the slightest about the goings-on of Tir Princes, those with a little more time in the game, a little more refined thinking, and those useful contacts, likely steer the gang -- overall -- in a vaguely "pro-Tir" or at least "maintain ties with those who are pro-Tir" direction.
