100% quest completion and some NPC dialogue.
Oh yes, they certainly have been helping. I'm not denying that. But it isn't the act of pure altruism you're presenting it as. I would recommend playing through the story again when you get the chance, and really paying close attention to what's going on. You might just see what I'm referring to, although to be honest I think you already know exactly what it is I am talking about.
Now you're just being openly disingenuous. You are both knowingly mischaracterizing the (stated) intent behind, proposed scale of, and (stated) intended targets of Project Meteor and attempting to infer that our current discussion about the Garleans is in any way related to the controversial nature of Endwalker outside the specific window of their involvement in it. Your own source on Project Meteor details its intended targets so far as the Garlean officials were aware, and "all of Eorzea" is not mentioned. You are fully aware that this entire discussion has been a thread derail, not an addition to what was already being considered. Given the content of your prior posts, it's rather pointless to pretend otherwise now. You are also now demanding sources despite already knowing full well where everything I mentioned came from, with you even having provided one of the same sources I used.
To be blunt, I've been under the impression you were approaching this debate in bad faith for quite some time now. Your own source shot down your argument pretty much as soon as you used it, but you kept trying to, despite it clearly saying beastmen and their eikons, insinuate the stated intent was to obliterate all of Eorzea with it. You also keep intentionally conflating the Garlean people with their rulers/military, when even the game itself has made the distinction between these groups very clear for quite a long time. It isn't like the average Garlean had any say in who their leaders were, let alone what they did.
