Thanks for the nod to this in an article, Riendeau! I personally have been thinking about this a lot around the recent Before the Storm press (I think I even mentioned it in the designated Waypoint thread, probably) and I’m still incredibly disappointed by the pushback I’ve seen some other places against even the concept of a labor dispute taking place in games.
To address this:
I would say that, personally, it does depend on the project, with a couple key consistencies. If they’re going to less-unionized country’s labor market to circumvent their own laws/local unions (which is the oldest trick in the book) then that’s absolutely worth criticizing and naming for what it is. You mentioned this in your post with the question about globally moving work to different places. So although you’re clearly aware, I do want to reiterate that tapping people from other countries to do jobs for less money because they don’t have 1) context for the strike or 2) many other options themselves is Scab Tactics 101 on part of the employers.
When it’s not an instance like that, I personally think it comes down to where the employees are locally based. Burch is from the United States and she pays taxes here. She’s employed here. She’s protected under the labor laws in her own country. The original LiS team needed United States voice actors and wanted to pull from the talent in the U.S. for exclusively creative reasons, as far as I know; if a company like Square Enix deliberately broke a seiyuu strike in Japan, by the same measure, I’d hope it’d get the same response here that Deck Nine(/Blind Light?)'s choice has.
TL;DR, there’s unions in a lot of countries and I think publishers that work in multiple countries should be prepared to deal with each and every one of them, no matter how many there are, to make sure their employees are represented fairly.
