Yes, she chose to flee Garlemald and hand over secrets that would result in her former comrades being slain. As a traitor and a saboteur it makes sense for her former allies to be displeased with her - and that's exactly the same reaction that we've seen from the likes of the Eorzean Alliance whenever they have been shown to hunt down traitors and saboteurs. They, too, had their reasons for seeking to flee. In the case of Yotsuyu and Misija, what the Garleans offered was far better than what their former people offered. Another saboteur that springs to mind is 'The Ivy' from way back in ARR.

Ultimately it's all a matter of perspective. There's no real winners or losers in war, history is written by the supposed 'victors' and hypocrisy is ever present on both sides in the pursuit of survival.

I'm not sure where the idea of 'stifling discussion' is coming from. That was not my intention. I merely assume that if people are weighing in on something then it's because they've experienced it already. If I went to go and discuss the latest episode of a TV show, I don't think it'd be unreasonable for me to be expected to have watched it.
